Power Guide
You can create and use a power strategy to plan your effort on a course. Your D2 Air X15 device uses your
FTP, the course elevation, and the projected time it will take you to complete the course to create a customized
power guide.
One of the most important steps in planning a successful power guide strategy is choosing your effort level.
Putting a harder effort into the course will increase the power recommendations, while choosing an easier effort
will reduce them (Creating and Using a Power Guide, page23). The primary goal of a power guide is to help you
complete the course based on what is known about your ability, not to achieve a specific target time. You can
adjust the effort level during your ride.
Power guides are always associated with a course and cannot be used with workouts or segments. You can
view and edit your strategy in Garmin Connect and sync it with compatible Garmin devices. This feature requires
a power meter, which must be paired with your device (Pairing Your Wireless Sensors, page88). After the
devices are paired, you can customize the optional data fields (Data Fields, page134).
Creating and Using a Power Guide
Before you can create a power guide, you must pair a power meter with your watch (Pairing Your Wireless
Sensors, page88). You must also have a course loaded to your Garmin Connect account (Creating a Course on
Garmin Connect, page108).

Swim Terminology
Length: One trip down the pool.
Interval: One or more consecutive lengths. A new interval starts after a rest.
Stroke: A stroke is counted every time your arm wearing the watch completes a full cycle.
Swolf: Your swolf score is the sum of the time for one pool length and the number of strokes for that length.
For example, 30 seconds plus 15 strokes equals a swolf score of 45. For open water swimming, swolf is
calculated over 25 meters. Swolf is a measurement of swimming efficiency and, like golf, a lower score is
better.
Critical swim speed (CSS): Your CSS is the theoretical speed that you can maintain continuously without
exhaustion. You can use your CSS to guide your training pace and monitor your improvement.
Stroke Types
Stroke type identification is available only for pool swimming. Your stroke type is identified at the end of a
length. Stroke types appear in your swimming history and in your Garmin Connect account. You can also select
stroke type as a custom data field (Customizing the Data Screens, page37).

Lactate Threshold
Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the bloodstream.
In running, this intensity level is estimated in terms of pace, heart rate, or power. When a runner exceeds the
threshold, fatigue starts to increase at an accelerating rate. For experienced runners, the threshold occurs at
approximately 90% of their maximum heart rate and between 10 km and half-marathon race pace. For average
runners, the lactate threshold often occurs well below 90% of maximum heart rate. Knowing your lactate
threshold can help you determine how hard to train or when to push yourself during a race.
If you already know your lactate threshold heart rate value, you can enter it in your user profile settings (Setting
Your Heart Rate Zones, page116). You can turn on the Auto Detection feature to automatically record your
lactate threshold during an activity.
Training 69
Training Status
These measurements are estimates that can help you track and understand your training activities. The
measurements require you to complete activities for two weeks using wrist-based heart rate or a compatible
chest heart rate monitor. Cycling performance measurements require a heart rate monitor and a power meter.
The measurements may seem inaccurate at first when the watch is still learning about your performance.
These estimates are provided and supported by Firstbeat Analytics. For more information, go to garmin.com
/performance-data/running.
Training status: Training status shows you how your training affects your fitness and performance. Your
training status is based on changes to your VO2 max., acute load, and HRV status over an extended time
period.
VO2 max.: VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram
of body weight at your maximum performance (About VO2 Max. Estimates, page65).
HRV: HRV is your heart rate variability status over the last seven days (Heart Rate Variability Status, page67).
Acute load: Acute load is a weighted sum of your recent exercise load scores including exercise duration and
intensity. (Acute Load, page71).
Training load focus: Your watch analyzes and distributes your training load into different categories based on
the intensity and structure of each activity recorded. Training load focus includes the total load accumulated
per category, and the focus of the training. Your watch displays your load distribution over the last 4 weeks
(Training Load Focus, page72).
Recovery time: The recovery time displays how much time remains before you are fully recovered and ready for
the next hard workout (Recovery Time, page74).
70 Training
Training Status Levels
Training status shows you how your training affects your fitness level and performance. Your training status is
based on changes to your VO2 max., acute load, and HRV status over an extended time period. You can use
your training status to help plan future training and continue improving your fitness level.
No Status: The watch needs you to record multiple activities over two weeks, with VO2 max. results from
running or cycling, to determine your training status.
Detraining: You have a break in your training routine or you are training much less than usual for a week
or more. Detraining means that you are unable to maintain your fitness level. You can try increasing your
training load to see improvement.
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.
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.
Productive: Your current training load is moving your fitness level and performance in the right direction. You
should plan recovery periods into your training to maintain your fitness level.
Peaking: You are in ideal race condition. Your recently reduced training load is allowing your body to recover
and fully compensate for earlier training. You should plan ahead, since this peak state can only be maintained
for a short time.
Overreaching: Your training load is very high and counterproductive. Your body needs a rest. You should give
yourself time to recover by adding lighter training to your schedule.
Unproductive: Your training load is at a good level, but your fitness is decreasing. Try focusing on rest, nutrition,
and stress management.
Strained: There is imbalance between your recovery and training load. It is a normal result after a hard training
or major event. Your body may be struggling to recover, so you should pay attention to your overall health.
Tips for Getting Your Training Status
The training status feature depends on updated assessments of your fitness level, including at least one VO2
max. measurement per week (About VO2 Max. Estimates, page65). Indoor run activities do not generate a VO2
max. estimate in order to preserve the accuracy of your fitness level trend. You can disable VO2 max. recording
for ultra run and trail run activities if you do not want those run types to affect your VO2 max. estimate (Activity
Settings, page38).
To get the most out of the training status feature, you can try these tips.
• At least one time per week, run or ride outdoors with a power meter, and reach a heart rate higher than 70% of
your maximum heart rate for at least 10 minutes.
After using the watch for one or two weeks, your training status should be available.
• Record all of your fitness activities on your primary training device, allowing your watch to learn about your
performance (Syncing Activities and Performance Measurements, page97).
• Wear the watch consistently while you sleep, to continue generating an up-to-date HRV status. Having a valid
HRV status can help maintain a valid training status when you do not have as many activities with VO2 max.
measurements.
Acute Load
Acute load is a weighted sum of your excess post-exercise oxygen consumption (EPOC) for the last several
days. The gauge indicates whether your current load is low, optimal, high, or very high. The optimal range is
based on your individual fitness level and training history. The range adjusts as your training time and intensity
increase or decrease.
Training 71
Training Load Focus
In order to maximize performance and fitness gains, training should be distributed across three categories: low
aerobic, high aerobic, and anaerobic. Training load focus shows you how much of your training is currently in
each category and provides training targets. Training load focus requires at least 7 days of training to determine
if your training load is low, optimal, or high. After 4 weeks of training history, your training load estimate will
have more detailed target information to help you balance your training activities.
Below targets: Your 4-week training load is lower than optimal in all intensity categories.
Low aerobic shortage: Try adding more low aerobic activities to provide recovery and balance for your higher
intensity activities.
High aerobic shortage: Try adding more high aerobic activities to help improve your lactate threshold and VO2
max. over time.
Anaerobic shortage: Try adding a few more intense, anaerobic activities to improve your speed and anaerobic
capacity over time.
Balanced: Your training load is balanced and provides all-around fitness benefits as you continue training.
Low aerobic focus: Your training load is mostly low aerobic activity. This provides a solid foundation and
prepares you for adding more intense workouts.
High aerobic focus: Your training load is mostly high aerobic activity. These activities help to improve lactate
threshold, VO2 max., and endurance.
Anaerobic focus: Your training load is mostly intense activity. This leads to rapid fitness gains, but should be
balanced with low aerobic activities.
Above targets: Your 4-week training load is higher than optimal.
Load Ratio
Load ratio is the ratio of your acute (short-term) training load to your chronic (long-term) training load. It's
helpful for tracking your training load changes.
Status Value Description

About Training Effect
Training Effect measures the impact of an activity on your aerobic and anaerobic fitness. Training Effect
accumulates during the activity. As the activity progresses, the Training Effect value increases. Training Effect
is determined by your user profile information and training history, and heart rate, duration, and intensity of your
activity. There are seven different Training Effect labels to describe the primary benefit of your activity. Each
label is color coded and corresponds to your training load focus (Training Load Focus, page72). Each feedback
phrase, for example, "Highly Impacting VO2 Max." has a corresponding description in your Garmin Connect
activity details.
Aerobic Training Effect uses your heart rate to measure how the accumulated intensity of an exercise affects
your aerobic fitness and indicates if the workout had a maintaining or improving effect on your fitness level.
Your excess post-exercise oxygen consumption (EPOC) accumulated during exercise is mapped to a range of
values that account for your fitness level and training habits. Steady workouts at moderate effort or workouts
involving longer intervals (>180 seconds) have a positive impact on your aerobic metabolism and result in an
improved aerobic Training Effect.
Anaerobic Training Effect uses heart rate and speed (or power) to determine how a workout affects your ability
to perform at very high intensity. You receive a value based on the anaerobic contribution to EPOC and the
type of activity. Repeated high-intensity intervals of 10 to 120 seconds have a highly beneficial impact on your
anaerobic capability and result in an improved anaerobic Training Effect.
You can add Aerobic Training Effect and Anaerobic Training Effect as data fields to one of your training screens
to monitor your numbers throughout the activity.
Training Effect Aerobic Benefit Anaerobic Benefit
From 0.0 to 0.9 No benefit. No benefit.
From 1.0 to 1.9 Minor benefit. Minor benefit.
From 2.0 to 2.9 Maintains your aerobic fitness. Maintains your anaerobic fitness.
From 3.0 to 3.9 Impacts your aerobic fitness. Impacts your anaerobic fitness.

Training Readiness
Your training readiness is a score and a short message that helps you determine how ready you are for training
each day. The score is continuously calculated and updated throughout the day using these factors:
• Sleep score (last night)
• Recovery time
• HRV status
• Acute load
• Sleep history (last 3 nights)
• Stress history (last 3 days)

To view historical training readiness scores, go to your Garmin Connect account.
Recovery Time
You can use your Garmin device with wrist-based heart rate or a compatible chest heart rate monitor to display
how much time remains before you are fully recovered and ready for the next hard workout.
NOTE: The recovery time recommendation uses your VO2 max. estimate and may seem inaccurate at first. The
device requires you to complete a few activities to learn about your performance.
The recovery time appears immediately following an activity. The time counts down until it is optimal for you to
attempt another hard workout. The device updates your recovery time throughout the day based on changes in
sleep, stress, relaxation, and physical activity.
74 Training
Recovery Heart Rate
If you are training with wrist-based heart rate or a compatible chest heart rate monitor, you can check your
recovery heart rate value after each activity. Recovery heart rate is the difference between your exercising heart
rate and your heart rate two minutes after the exercise has stopped. For example, after a typical training run,
you stop the timer. Your heart rate is 140bpm. After two minutes of no activity or cool down, your heart rate
is 90 bpm. Your recovery heart rate is 50 bpm (140 minus 90). Some studies have linked recovery heart rate to
cardiac health. Higher numbers generally indicate healthier hearts.
TIP: For best results, you should stop moving for two minutes while the device calculates your recovery heart
rate value.
NOTE: Your recovery heart rate is not calculated for low-impact activities, such as yoga.
History
History includes time, distance, calories, average pace or speed, lap data, and optional sensor information.

• Make sure you have a running dynamics accessory, such as the HRM 600, HRM-Fit, or HRM-Pro series
accessory.
• Pair the running dynamics accessory with your watch again, according to the instructions.
• If you are using an HRM 600 accessory, pair it with your watch using the secure Bluetooth connection, rather
than the open connection.
For more information about connection types, go to garmin.com/hrm_connection_types.
• If you are using an HRM-Fit or HRM-Pro series accessory, pair it with your watch using ANT+ technology,
rather than Bluetooth technology.
• If the running dynamics data display shows only zeros, make sure the accessory is worn right-side up.
NOTE: Some metrics do not appear while walking (Running Dynamics, page88).
Running Power
Garmin running power is calculated using measured running dynamics information, user mass, environmental
data, and other sensor data. The power measurement estimates the amount of power a runner applies to the
road surface, and it is displayed in watts. Using running power as a gauge of effort may suit some runners
better than using either pace or heart rate. Running power can be more responsive than heart rate for indicating
the level of effort, and it can account for the uphills, downhills, and wind, which a pace measurement does not
do. For more information, go to garmin.com/performance-data/running.
Running power can be measured using a compatible running dynamics accessory or the watch sensors. You
can customize the running power data fields to view your power output and make adjustments to your training
(Data Fields, page134). You can set up power alerts to be notified when you reach a specified power zone
(Activity Alerts, page40).
Running power zones use default values based on gender, weight, and average ability, and may not match your
personal abilities. You can manually adjust your zones on the watch or using your Garmin Connect account
(Setting Your Power Zones, page117).

Running Power Settings
From the watch face, press , select Activities, select a running activity, press , select the activity settings, and
select Running Power.
Status: Enables or disables recording Garmin running power data. You can use this setting if you prefer to use
third-party running power data.
Source: Allows you to select which device to use to record running power data. The Smart Mode option
automatically detects and uses the running dynamics accessory, when available. The watch uses wrist-based
running power data when an accessory is not connected.
Accound for Wind: Enables or disables using wind data when calculating your running power. Wind data is a
combination of the speed, heading, and barometer data from your watch and the available wind data from
your phone.
Chest Heart Rate While Swimming
The HRM 600, HRM-Pro series, HRM-Swim
™
, and HRM-Tri
™
heart rate accessories record and store your heart
rate data while you are swimming. To view your heart rate data, you can add heart rate data fields (Customizing
the Data Screens, page37).
NOTE: Chest heart rate data is not visible on compatible watches while the heart rate monitor is underwater.
You must start a timed activity on your paired watch to view stored heart rate data later. During rest intervals
when out of the water, the heart rate accessory sends your heart rate data to your watch. Your watch
automatically downloads stored heart rate data when you save your timed swim activity. Your heart rate
accessory must be out of the water, active, and within range of the watch (3m) while data downloads. Your
heart rate data can be reviewed in the watch history and on your Garmin Connect account.
If both wrist-based heart rate and chest heart rate data are available, your watch uses the chest heart rate data.

Pulse Oximeter
Your watch has a wrist-based pulse oximeter to gauge the peripheral saturation of oxygen in your blood (SpO2).
As your altitude increases, the level of oxygen in your blood can decrease. Knowing your oxygen saturation can
help you determine how your body is adjusting to high altitudes. During a flight, the watch automatically takes
pulse oximeter readings more frequently, so you can monitor your SpO2 percentage.
You can manually begin a pulse oximeter reading by viewing the pulse oximeter glance (Getting Pulse Oximeter
Readings, page104). You can also turn on all-day readings (Setting the Pulse Oximeter Mode, page104). When
you view the pulse oximeter glance while you are not moving, your watch analyzes your oxygen saturation and
your elevation. The elevation profile helps indicate how your pulse oximeter readings are changing, relative to
your to elevation.
On the watch, your pulse oximeter reading appears as an oxygen saturation percentage and color on the graph.
On your Garmin Connect account, you can view additional details about your pulse oximeter readings, including
trends over multiple days.

Intensity Minutes
To improve your health, organizations such as the World Health Organization recommend at least 150 minutes
per week of moderate intensity activity, such as brisk walking, or 75 minutes per week of vigorous intensity
activity, such as running.
The watch monitors your activity intensity and tracks your time spent participating in moderate to vigorous
intensity activities (heart rate data is required to quantify vigorous intensity). The watch adds the amount of
moderate activity minutes with the amount of vigorous activity minutes. Your total vigorous intensity minutes
are doubled when added.
Earning Intensity Minutes
Your D2 Air X15 watch calculates intensity minutes by comparing your heart rate data to your average resting
heart rate. If heart rate is turned off, the watch calculates moderate intensity minutes by analyzing your steps
per minute.
• Start a timed activity for the most accurate calculation of intensity minutes.
• Wear your watch all day and night for the most accurate resting heart rate.
Sleep Tracking
While you are sleeping, the watch automatically detects your sleep and monitors your movement during your
normal sleep hours. You can set your normal sleep hours in the Garmin Connect app or in the watch settings.
Sleep statistics include total hours of sleep, sleep stages, sleep movement, and sleep score. Your sleep coach
provides sleep need recommendations based on your sleep and activity history, HRV status, and naps (Glances,
page44). Naps are added to your sleep statistics, and can also impact your recovery. You can view detailed
sleep statistics on your Garmin Connect account.
NOTE: You can use do not disturb mode to turn off notifications and alerts, with the exception of alarms (Using
Do Not Disturb Mode, page55).

About Heart Rate Zones
Many athletes use heart rate zones to measure and increase their cardiovascular strength and improve their
level of fitness. A heart rate zone is a set range of heartbeats per minute. The five commonly accepted
heart rate zones are numbered from 1 to 5 according to increasing intensity. Generally, heart rate zones are
calculated based on percentages of your maximum heart rate.
Fitness Goals
Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying
these principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve cardiovascular capacity and strength.
If you know your maximum heart rate, you can use the table (Heart Rate Zone Calculations, page117) to
determine the best heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the calculators available on the Internet. Some gyms
and health centers can provide a test that measures maximum heart rate. The default maximum heart rate is
220 minus your age.

Appendix 131
Color Gauges and Running Dynamics Data
The running dynamics screens display a color gauge for the primary metric. You can display cadence, vertical
oscillation, ground contact time, ground contact time balance, or vertical ratio as the primary metric. The color
gauge shows you how your running dynamics data compare to those of other runners. The color zones are
based on percentiles.
Garmin has researched many runners of all different levels. The data values in the red or orange zones are
typical for less experienced or slower runners. The data values in the green, blue, or purple zones are typical
for more experienced or faster runners. More experienced runners tend to exhibit shorter ground contact times,
lower vertical oscillation, lower vertical ratio, and higher cadence than less experienced runners. However, taller
runners typically have slightly slower cadences, longer strides, and slightly higher vertical oscillation. Vertical
ratio is your vertical oscillation divided by stride length. It is not correlated with height.
Go to garmin.com/runningdynamics for more information on running dynamics. For additional theories and
interpretations of running dynamics data, you can search reputable running publications and websites.

Ground Contact Time Balance Data
Ground contact time balance measures your running symmetry and appears as a percentage of your total
ground contact time. For example, 51.3% with an arrow pointing left indicates the runner is spending more time
on the ground when on the left foot. If your data screen displays both numbers, for example 48–52, 48% is the
left foot and 52% is the right foot.

Ground Contact Time Balance >52.2%L 50.8–52.2%L 50.7%L–50.7%R 50.8–52.2%R >52.2%R
While developing and testing running dynamics, the Garmin team found correlations between injuries and
greater imbalances with certain runners. For many runners, ground contact time balance tends to deviate
further from 50–50 when running up or down hills. Most running coaches agree that a symmetrical running
form is good. Elite runners tend to have quick and balanced strides.
You can watch the gauge or data field during your run or view the summary on your Garmin Connect account
after your run. As with the other running dynamics data, ground contact time balance is a quantitative
measurement to help you learn about your running form.
