Your VO2 max score is the key to seeing, understanding and, more importantly managing your personal fitness level. At a technical level, it describes the maximum rate at which you can bring oxygen into your body, transport it to your muscles and use it for efficient aerobic energy production. At a personal level, it is a remarkable and versatile tool with a variety of health and performance implications.
When it comes to understanding your VO2 max score, it’s easy to remember that low VO2 max scores represent poor fitness levels, and higher VO2 max scores indicate greater performance capacity. Like most aspects relating to physical performance, there is a genetic dimension to how efficiently your body uses oxygen and, by extension, your VO2 max range. That said, your VO2 max score is dynamic, and it reacts to how you live and train. With the right approach, practically everyone can improve their VO2 max score.
The people least likely to be able to improve their VO2 max are elite athletes, because they are already in excellent shape. This is great news for everyone else.
Studies have shown that being more active can make you happier and live longer. VO2 max is a key metric used to study and verify this from a scientific perspective. If you’re looking to improve, your device also offers the tools you need to get things headed in the right direction.
For those interested in performance, VO2 max can be used in a slightly different way. The more oxygen your body can use during exercise, the more power you can generate and, therefore, the faster you can run during a race.
Once a VO2 max is established, your device can provide a target race time based on your current state of fitness. Projected race times can be viewed for 5K, 10K, half-marathon and marathon distances, which will get faster or slower as your fitness goes up or down. At all race distances, but especially in longer races such as marathons, there are many important and necessary factors for success that go beyond just aerobic fitness; that’s why it is important to complete proper training for an event to give yourself the best shot at reaching your predicted race times. And remember, these times are just predictions, but they give you a good idea of the kind of performances you can reasonably expect, given your physiological data. They also provide a terrific goal to try and reach.
For a real-time assessment of your current ability to perform, look at your performance condition. During the first 6 to 20 minutes of your run, this metric analyses pace, heart rate and heart rate variability. The resulting number is a real-time assessment of the deviation from your baseline VO2 max, with each point on the scale representing about 1% of your VO2 max. The higher the number, the higher you can expect to perform. Keep in mind that your results may vary a bit during your first few runs with a new device, since it’s still learning your fitness level. This will stabilise, and then checking your performance condition will become a reliable day-to-day indicator of your capability.
In addition to the alert during the first part of your run, you can add performance condition as a data field to your training screens, and keep an eye on it as your run unfolds. The value may move around slightly as you encounter hills or strong winds, but it will trend down once you have been going hard for a while if the run starts to take a toll on you. This is an objective way to keep an eye on how your ability to perform is or isn’t declining as you go, because it’s telling you if your body is working harder than normal to run at your current pace. So, performance condition can give you a bit of an early “wall” warning and allow you to adjust your tactics before you hit that wall too hard.
If you’re like most people, you train because you want results. Because of how our bodies work, the type of training you do determines the type of results you can expect and the types of performances you will be well prepared for in the future.
Training effect is the metric that gives you a sneak peek at how each training session is expected to impact your future fitness levels. Of course, to get the full benefits of your training, it’s important to incorporate a proper recovery schedule.
One of the most common usages of training effect is to coordinate and balance workouts that maintain and improve your current fitness level (see VO2 max).
Training effect builds over the course of your workout and is updated in real time. This means you can use it as an on-the-go resource to tailor your workout to your needs. You can push yourself harder when you are striving to improve and slow down before you wander into the overreaching range, where the results may not be what you wanted.
Aerobic Training Effect
- Develops aerobic energy production
- Utilization of fat for energy
- Endurance and stamina
- Prolonged performance capacity
Available on select Garmin watches, this measures the aerobic benefit of exercise, which should correlate with the fitness improvement you expect to get from it. When you crush a difficult run, you’ve likely given yourself a bigger dose of aerobic exercise and, therefore, a bigger training effect. What good is this information for you? Well, training effect uses your heart rate to measure the accumulated intensity of exercise on your aerobic fitness and gives you a good indication of whether you’re maintaining your current fitness level or improving it.
Aerobic training effect is the same as the original training effect feature offered on many earlier Garmin watches, except the scale has been modified slightly to account for — let’s face it — those really short or really easy activities that have no meaningful training effect. In other words, we added a “0” at the bottom of the scale.
Technically speaking, aerobic training effect is the excess post-exercise oxygen consumption EPOC accumulated during exercise, mapped onto a 0-to-5 scale that accounts for your fitness level and training habits. Typically, as you get fitter, you need larger “doses” of exercise to continue seeing improvement. So, while an exercise session generating an EPOC of 60 ml-O2/kg might have given you a great training benefit when you were out of shape, it might not do very much for you once you have whipped yourself into wickedly good shape. Training effect reflects this reality by giving a higher number in the first case than in the second case.
Note: The training effect scale for both aerobic and anaerobic is: 0 – None, 1 – Minor, 2 – Maintaining, 3 – Improving, 4 – Highly Improving, 5 – Overreaching.
Anaerobic Training Effect
- Develops anaerobic energy production
- Sprinting abilities
- Fatigue resistance
- Maximal performance capacity
While there isn’t a specific metric tied to it, the aspect of performance most easily associated with anaerobic training effect is your ability to perform and repeat sprints. The flow of a football game is a good point of reference here, where the activity of the game is punctuated with sudden flurries of high-intensity activity.
Your body’s most efficient method of transforming fuel into energy requires oxygen, but sometimes your demand for energy exceeds the rate at which enough oxygen is immediately available. Luckily, your body has a backup process ready and waiting. While not nearly as efficient, the anaerobic energy process can jump into action and keep you going. The downside is that it becomes depleted quickly.
Whereas aerobic training effect ties nicely with increasing your aerobic fitness level — expressed in terms of VO2 max — things are a little more complicated with accounting for improvements on the anaerobic side of things.
By analysing both heart rate and speed (or power, in the case of cycling) the anaerobic training effect feature quantifies the anaerobic contribution to EPOC made during these periods of exertion. The higher the anaerobic training effect, the greater expected benefit to your anaerobic athletic capability. High-intensity intervals, for example, have been shown to improve several components related to your ability to perform, and anaerobic training effect quantifies this for you. However, the feature goes one step further. By analysing the type of workout you did, it can tell you more specifically how the workout helped you. For example, if it were detected that you completed several high-speed repeats, you might get an anaerobic training effect of 3.5 saying, “This activity improved your anaerobic capacity and speed due to several high-speed/power repeats.”
Training Effect Samples
The following table should give you an idea of the typical aerobic and anaerobic training effect you can expect from a good workout.
|Run Type||Typical Aerobic TE||Typical Anaerobic TE|
|Long, slow distance||2.0 - 3.0Maintaining Aerobic Fitness||0No Anaerobic Benefit|
|20-minute threshold||3.5+Improving Lactate Threshold||0No Anaerobic Benefit|
|Lactate threshold intervals||3.0+Improving Lactate Threshold||0 - 2.0Minor Anaerobic Benefit|
|Sprint intervals10 x 50m @|
150-200% VO2 max
|0 - 2.0Minor Aerobic Benefit||2.0 - 3.0Maintaining Speed|
|Speed intervals10 x 400m @|
100-105% VO2 max
|2.0 - 4.0Improving Aerobic Fitness||3.0 - 4.0Improving Economy and Anaerobic Fitness|
|Speed intervals10 x 400m @|
110-115% VO2 max
|2.0 - 4.0Improving VO2 Max||4.0+Highly Improving|
|800m race||2.0+Maintaining Aerobic Fitness||2.5+Maintaining Anaerobic Fitness|
|5K race||3.5+Improving VO2 Max||1.0 - 2.0Minor Anaerobic Benefit|
|10K race||4.0+Highly Improving VO2 Max||0.0 - 2.0Minor Anaerobic Benefit|
|Note that the above training effect values and phrases are illustrative examples. Your experience may differ depending on your personal training habits. For example, if you incorporate strides or faster fartleks into your distance runs, these can add an anaerobic training effect.|
|As with many Garmin Firstbeat features, it may take several training sessions for the watch to learn your fitness parameters and produce the most accuraute results. While the device is still learning about you, you may see uncharacteristic training effect values.|
Your lactate threshold is that specific level of effort or pace when fatigue accelerates. For a well-trained runner, this usually occurs when they’re at about 90% of their maximum heart rate corresponding to a pace somewhere between 10K and half-marathon race pace. For a less experienced runner, the lactate threshold is often below 90% of maximum heart rate.
Select Garmin devices can detect your lactate threshold either through a guided workout or automatically during a normal run. Either way, by gathering heart rate data across a range of paces, the device will estimate your lactate threshold both in terms of a running pace and a heart rate level in beats per minute. For best results, it’s very beneficial to go for several runs after first taking the watch into use in order for your device to accurately learn your overall fitness level. Then, once this is well established, subsequent lactate threshold results will be more accurate than they might be initially.
Historically, athletes hoping to utilise their lactate thresholds to personalise their training regimens needed blood testing to assess the amount of lactate accumulating during their training sessions. This process limited the number of athletes who had access to this valuable training information.
The Firstbeat method of lactate threshold detection used in Garmin devices relies on the fact that your respiration rate — how hard you are breathing — can be detected through analysis of your heart rate variability. The process of inhalation and exhalation produces tiny changes in the interval between heartbeats (HRV). When these variations are decoded and combined with other performance data, your device can recognise the simultaneous changes in your heart rate to indicate when you are performing above your lactate threshold.
How can this help you? Your lactate threshold is the single best determinant of your endurance performance capacity. As your ability to cover long distances at a faster pace increases, you’ll see increases in your lactate threshold. This metric is also a valuable resource for recognising the personal training zones that will boost your individual performance. That’s because your training will be based on real physiological state transitions in your body instead of arbitrary percentages of your maximum heart rate.
Knowing your lactate threshold lets you train with more precision. Many coaches prescribe some running at lactate threshold as part of an overall training program. The lactate threshold feature in compatible Garmin devices helps you determine where your threshold is — without paying for an expensive lab test involving multiple blood samples.
Recovery is a critical, but often overlooked, portion of the training process. The recovery period is marked by adaptation of your body in response to training and the replenishment of vital resources. In fact, insufficient recovery can lead to missing out on gains in fitness and performance entirely. Keeping track of your recovery levels will reveal when training hard will be beneficial and ensure your work is rewarded with the results you expect. You gain the ability to update and optimise your training programs with confidence.
After each workout, your device reveals the number of hours before you will be back near 100% and capable of performing a hard workout or running a race. Provided by Firstbeat, the calculation is produced and personalised using a unique digital model of your physiology. It utilises a combination of the session’s training effect score, performance and fitness level assessments performed during the session and the number of hours of recovery time remaining on your clock at the start of your workout.
Recovery time ranges up to 4 days.
For best results, it’s beneficial to first go for several runs with your watch in order for the device to accurately learn your overall fitness level. Once this is established, subsequent recovery time results may be more accurate.
Want to look at the bigger picture? This is where you need to go. Training load is a measure of the total volume of your training for the last 7 days. Furthermore, your compatible Garmin device compares this weekly training load to your longer-term training load — also taking into account your fitness level — and shows you if this load is in the optimal range. The volume of a workout is the EPOC it creates as estimated from heart rate data gathered during the workout. Your current training load then is just the sum of EPOC measurements for the last 7 days.
It’s true that pushing yourself is the way to get results, but overreaching and training too hard is a real possibility that is counterproductive and could even lead to injury. So look carefully at your training load, and see if you’re doing too much, too little or just the right amount.
The available training load ranges are:
High – Based on your current fitness level and recent training habits, your training load may be too high to produce positive results.
Optimal – This range is ideal for maintaining and improving your fitness level. Keep up the good work!
Low – Your training load is low for your current fitness level and training habits. If you stay in this range, you are unlikely to see further improvement.
Training status is the first feature offered by Garmin that truly analyses not only today’s run but also your longer-term training habits. This provides you with powerful insight into how your training is really going. If other metrics offer you a window into the process, training status knocks down the walls to let you enjoy the panoramic view.
Is your current training intense enough, or long enough, to help improve your fitness? How do you know if you’re working hard enough to make a difference in the long run or if you’re not pushing yourself hard enough? Training status helps you make decisions about future training by automatically taking into account changes in fitness level, your current acute (7-day) training load and any change in training load with respect to previous training. In essence, it tells you the effectiveness of your current training and provides guidance to help you improve your training decisions.
Provided by Firstbeat, the calculation utilises several dimensions of a personalised model of your physiology. Changes in your VO2 max fitness level in light of your recent training loads over time indicate the effectiveness of your training.
The dynamic and interwoven nature of our physiology often makes the process of training seem more like art than science. On the surface, what we expect isn’t always what we get, and what we get isn’t always what we expect.
To explain in simple terms, when you stop training, your fitness level will decrease, but depending on your previous training load, a break from normal training routines may result in an increase in fitness level. Similarly, it’s expected that regular hard training will improve our fitness levels, but watch out — push too hard too often, and your fitness level will start to decrease due to the overtraining phenomenon.
As an example of how this works, imagine that you’ve been training consistently for a number of weeks, and your fitness with normal, small day-to-day ups and downs is nevertheless increasing. This trend is automatically identified and your current training will be classified as “productive.” Similarly, you could find yourself training very hard but with your fitness starting a pattern of decline. In this situation, your training would be identified as “overreaching,” and additional recovery will be recommended.
The recognised training states are below.
Peaking – You are in ideal race condition! Your recently reduced training load is allowing your body to recover and fully compensate for earlier training. Be sure to think ahead, since this peak state can only be maintained for a short time.
Productive – Keep up the good work! Your training load is moving your fitness in the right direction. Be sure to plan recovery periods into your training to maintain your fitness level.
Maintaining – Your current training load is enough to maintain your fitness level. To see improvement, try adding more variety to your workouts or increasing your training volume.
Recovery – Your lighter training load is allowing your body to recover, which is essential during extended periods of hard training. You can return to a higher training load when you feel ready.
Unproductive – Your training load is at a good level, but your fitness is decreasing. Your body may be struggling to recover, so pay close attention to your overall health, including stress, nutrition and rest.
Detraining – You’ve been training much less than usual for a week or more, and it’s affecting your fitness. Try increasing your training load to see improvement.
Overreaching – Your training load is very high and has become counterproductive. Your body needs a rest. Give yourself time to recover by adding lighter training to your schedule.
No Status – You typically need a week or two of training history, including recent activities with VO2 max results from running or cycling, before we can determine your training status.
HRV Stress Test Stress Score in Older Products
If you’re wondering whether your body is ready for a hard run or in need of a lighter effort, it might be time to check your stress score. When you’re fresh and rested inside and out, you’re better able to absorb the training effect from a tough workout. However, the same hard workout can be counterproductive if you’re tired or on the verge of overtraining. Your stress score is calculated during a 3-minute test during which your heart rate variability HRV is analysed. The resulting stress score is displayed as a number from 0 to 100, with a lower number indicating a lower stress state. This measurement helps you assess what level of activity your body is ready for. More accurate results are gathered by taking the test at the same time and under the same conditions every day (recommended prior to the workout, not after.) This also helps you get a feel for your own day-to-day and week-to-week variations.
You are required to stand to take the HRV stress test, because that makes the test more sensitive to low and medium levels of stress. When you are lying down, moderate levels of stress may not be revealed, but standing puts a slight load on your cardiovascular system. That load causes a meaningful drop in HRV when you have a moderate amount of stress compared to very low stress.
Heart Rate Variability HRV
Your heart does not beat in a perfectly regular rhythm as would a metronome, and, in fact, beat-to-beat variations in your heart rate are healthy and normal. To understand more about how Garmin and Firstbeat use heart rate variability to give you better information about the state of your body, start with why heart rate variability exists.
Your heart is controlled by your autonomic nervous system (ANS), which is the involuntary part of your nervous system. Furthermore, there are 2 branches of the ANS called the sympathetic and parasympathetic branches. The sympathetic branch of your ANS is active when you’re under some kind of stress. It is the part of your ANS that puts all systems on alert. By contrast, the parasympathetic branch is the more relaxed part that just hums along when you are relaxed and not about to be charged by a mountain lion. When the sympathetic branch is more active, your heart rate typically increases, and it beats in more regular rhythm — meaning HRV decreases.
On the other hand, when the parasympathetic branch is more active, your heart rate decreases, and it beats when it gets around to it to meet the body’s needs, but not on such a strict schedule as when the sympathetic branch is in charge. In other words, HRV increases. Because of these characteristics, HRV is a great indicator of the balance between the activity of the 2 branches of the autonomic nervous system, and therefore it’s an indirect measurement of stress. Higher HRV means lower stress.
There are many different statistical methods used to characterise HRV, but the HRV stress test (formerly called stress score) feature makes life a lot easier by putting your stress on an easy-to-understand 0-to-100 scale specifically designed to be another tool for you to assess how your body is doing and how it’s handling training stress and life stress.
Although HRV decreases as you begin to exercise and continues to decline as you go harder, it still yields useful information even when you’re running fast. Available on some Garmin devices, the lactate threshold feature uses a Firstbeat feature that looks for a point of increasing HRV that corresponds closely to your lactate threshold heart rate.
Excess post-exercise oxygen consumption is the phenomenon where for a period of time after exercise, your body will continue to use oxygen at a higher rate than it would otherwise at rest. This makes sense. When you exercise, you disturb your body’s usual state, and this disturbance requires your body to do some extra work to put things back to normal. In fact, the point of training is that after exercise, your body will build itself back up to normal and then some. It is the “and then some” — also called “supercompensation” — that makes you a little fitter and faster than you were before.
Since the oxygen used by your body is related directly to the amount of energy it uses, the EPOC measurement is perfect for quantifying how much your body’s normal state (homeostasis) is disturbed by a session of exercise. In other words, EPOC is a great measure for exercise volume or dose, since it quantifies how much work your body had to do to get back to normal — and then some.
Directly measuring EPOC requires fancy laboratory equipment and a lot of time. However, Firstbeat created a patented method for estimating EPOC from your heart rate data during exercise. These EPOC estimates are at the core of how we determine your training effects, weekly training load and training status.
Ground Contact Time
This is the amount of time in each step that you spend on the ground while running. Ground contact time is typically pretty short, so it is measured in milliseconds. In fact, ground contact time tends to be especially short for elite runners, they will often have ground contact times of less than 200 ms. Virtually all experienced runners have ground contact times under 300 ms, likely because they have learned to “pick up” their feet quickly and not to over-stride as they are landing. Over-striding describes a running style where the foot lands too far in front of the body leading to braking forces at impact and, typically, longer ground contact times.
Ground Contact Time Balance
By monitoring the balance between your left and right foot ground contact time (GCT), this measures your symmetry as you run. On your Garmin watch, it’s always displayed as a percentage greater than 50% with an arrow to the left or right, to show which foot is on the ground longer. For most people, a more symmetrical running form is preferable. Colour gauges on Garmin watches and Garmin Connect™ show how balanced you are compared to other runners. Many runners report that GCT balance tends to deviate farther from 50/50 when they run up or down hills, when they do speed work or when they are fatigued. Anecdotally, some runners also notice that injuries are reflected in greater imbalance.
Simply put, this is how many steps you take per minute, counting both feet. It’s a commonly measured running metric and can tell you a lot about your form. For example, at a given pace, quicker cadence and shorter stride length result in smaller forces at many places throughout the body, such as at the ankles, knees and hips. The reduced magnitude of these forces is widely believed by experts to also reduce injury risk. It’s clear that running cadence can be increased only so far, but for more injury prone runners in particular, working on increased cadence could be beneficial. An often-cited target for running cadence is 180 steps per minute, though taller runners tend to have somewhat slower cadence. Interestingly, higher cadence is also associated with lower vertical oscillation and shorter ground contact time.
Another key part of measuring your running form — stride length — is how far you travel with each left and right step. It’s shown at the end of your run or as an in-activity data field you can view as you run. Later, you can view this data in more detail on Garmin Connect™ to see how your stride length varies with your pace, cadence, elevation or other metrics. Your stride length is dependent on a number of factors, including body morphology, muscular strength and flexibility.
This reflects the amount of “bounce” in each step while you run. Measured at the torso, it tells you, in centimeters, how much distance you are travelling up and down with each step. Many running coaches believe that lower vertical oscillation is more economical, because less energy is wasted going up and down. Garmin has researched many runners of all different levels. In general, more experienced runners tend to have lower vertical oscillation. However, faster paces often come at a cost of somewhat higher vertical oscillation. Vertical ratio (see below) takes this into account. Another advantage of lower vertical oscillation is that it typically means less stress on the lower body at impact.
This reflects your running efficiency based on how well you propel yourself forward with each stride. Vertical ratio is the amount of “bounce” in your stride, divided by your stride length, then expressed as a percent. Since stride length is the horizontal movement of running, it’s the benefit of the action, whereas vertical oscillation is one of the energy costs of running. A low vertical ratio number indicates a small cost for a large benefit. That means more efficient running.
For years, elite cyclists have used power data as the most reliable way to measure the actual exercise load of their ride. Now you, too, can train with power on your runs by downloading the Running Power app from the Connect IQ™ store onto your compatible watch. The Running Power app accounts for multiple factors to provide a more accurate and responsive exercise load calculation.
Developed by Garmin Labs, the Running Power app taps into metrics — such as pace, vertical oscillation, grade and even local wind conditions — to calculate the amount of power you’re applying at the ground as you run. When you know how much power you’re expending from minute to minute and mile to mile, you’re better able to pace yourself, which can help keep you from tiring out too quickly.
Think of your body’s energy as the battery of your smartphone. You can turn up the screen’s brightness all the way, but, as a result, the battery won’t last as long. Or you can conserve battery by dimming the screen and getting a longer battery life. Likewise, by getting to know your body and its power output while running in different conditions, you can monitor this data to conserve your energy. For marathons and other long-distance runs, this can help you fine-tune your training and performance on race day.
This running power model from Garmin determines the propulsive power applied at the road by considering the major components of the work done during running. These components, how they change and the data used to compute them are listed in the table below.
|Component of Running Power||What is it?||Source of Data Used to Compute|
|Kinetic Power||Power required to change your pace||Speed from the watch|
|Potential Power||Power required to run up or down a hill||Elevation data from the barometer on the watch|
|Potential Power||Power required to run up or down a hill||Elevation data from the barometer on the watch|
|Horizontal Oscillation Power||Power required for horizontal oscillation on each step (you brake a bit when you hit the ground, then accelerate again as you push off)||Speed from the watch Running dynamics from an HRM-Run, HRM-Tri or Running Dynamics Pod|
|Wind/Air Power||Power to overcome air resistance — greater if running into a headwind and less if you are running with the wind at your back|
- Speed from the watch
- Heading from the watch
- Heading from the watch
- Barometric data to detect local conditions
|Note: The equations to compute these components of running power also require some constant values such as your weight, acceleration due to gravity and the density of air.|
Following are examples of the contributions of the components of running power from a tester with cadence in the range of 162-182, vertical oscillation 6.2 – 8.9 cm, and GCT in the range of 262 – 296 ms.
This chart isolates some of the elements that contribute to running power to illustrate their effects on the total. In reality, multiple elements move together. For example, as you speed up, your cadence typically also increases and your GCT decreases. On an uphill, you might slow down and your vertical oscillation may decrease. The app is continually accounting for all these elements to compute the total running power.
So what does this mean for you? As you run, you will see that running power responds quickly when you speed up or slow down. You’ll also find that running power is higher when you’re running up hills than when you’re running at the same pace on flat ground. Similarly, running power will decrease when you run down a hill — though not by as much. In this way, you can use running power in addition to pace to help manage your effort over varying terrain.
With the wind power feature enabled, the Running Power app can even help you gauge your effort when running on a windy day. Wind can have a large effect on the effort required to maintain your usual pace, which shouldn’t surprise you if you’ve ever run into a stiff headwind. The Running Power app uses your heading from GPS and reported wind conditions for your area, augmented by data from the barometer on your watch, to determine how much wind you’re likely experiencing. Try running back and forth on a windy stretch of road and you will see how much higher your power is when you run into the wind. If you typically run in sheltered areas, or you just don’t want the app to account for wind, simply disable this feature within the app settings in the Garmin Connect™ Mobile app.
Many runners ask how running power correlates with heart rate. The 2 factors are certainly related as your muscles require more oxygen when they are generating more power. When viewing your charts post-run, you will see that when power goes up, heart rate follows a little while after. Avoiding this delay in response to changes (such as pace, hills or wind) is one of the advantages of using power rather than heart rate to gauge your effort when you’re running. Also, running power doesn’t depend on physiological factors — such as hydration level or how well-rested you are — the way heart rate does.
Many runners are also surprised that their running power is so much higher than their bike power. In fact, running power is expected to be higher than bike power because metabolic efficiency is much higher for running (around 40-45%) than for cycling (around 20-25%). This means that athletes can convert the same amount of oxygen into more power when running than we can do when cycling. Or, thinking in terms of heart rate, we can produce more power for the same heart rate. This is primarily because when we run, we benefit from passive recoil of elastics elements such as tendons. Simply put, energy is stored when we land and returned as we push off. The same is not true for cycling. For more information on this, refer to our FAQs.
To help you train with running power, you can choose to download apps to show Current Running Power, Lap Running Power, Last Lap Running Power, Average Power or all 4 of those at once. Some runners also use zones or alerts to monitor their running power. The app settings enable you to set up 5 custom running power zones and/or high and low running power alerts to help you keep your running power within a target range.
If you already own the right Garmin devices, adding power to your run is free. All you need is a compatible Garmin watch¹ and 1 of these 3 accessories: HRM-Run, HRM-Tri or the Running Dynamics Pod. Download the Running Power app now to get access to real-time power data.
