percentage. You should remain stationary for up to 30 seconds while the device reads your blood oxygen
saturation.

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.

Jumpmaster
WARNING
The jumpmaster feature is for use by experienced skydivers only. The jumpmaster feature should not be used
as a primary skydiving altimeter. Failure to input the appropriate jump related information can lead to serious
personal injury or death.
The jumpmaster feature follows military guidelines for calculating the high altitude release point (HARP). The
watch detects automatically when you have jumped to begin navigating toward the desired impact point (DIP)
using the barometer and electronic compass.
Planning a Jump

2 Enter the jump information (Entering Jump Information, page 30).
The device calculates the HARP.
3 Select GO TO HARP to start navigation to the HARP.
Activities and Apps 29
Jump Types
The jumpmaster feature allows you to set the jump type to one of three types: HAHO, HALO, or Static. The jump
type selected determines what additional setup information is required. For all jump types, drop altitudes and
opening altitudes are measured in feet above ground level (AGL).
HAHO: High Altitude High Opening. The jumpmaster jumps from a very high altitude and opens the parachute at
a high altitude. You must set a DIP and a drop altitude of at least 1,000 feet. The drop altitude is assumed to
be the same as the opening altitude. Common values for a drop altitude range from 12,000 to 24,000 feet
AGL.
HALO: High Altitude Low Opening. The jumpmaster jumps from a very high altitude and opens the parachute at
a low altitude. The required information is the same as the HAHO jump type, plus an opening altitude. The
opening altitude must not be greater than the drop altitude. Common values for an opening altitude range
from 2,000 to 6,000 feet AGL.
Static: The wind speed and direction are assumed to be constant for the duration of the jump. The drop altitude
must be at least 1,000 feet.

Performance Measurements
These performance measurements are estimates that can help you track and understand your training activities
and race performances. The measurements require a few activities using wrist-based heart rate or a compatible
chest heart rate monitor. Cycling performance measurements require a heart rate monitor and a power meter.
These estimates are provided and supported by Firstbeat Analytics
™
. For more information, go to garmin.com
/performance-data/running.
NOTE: The estimates may seem inaccurate at first. The watch requires you to complete a few activities to learn
about your performance.
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, page 58).
Predicted race times: Your watch uses the VO2 max. estimate and your training history to provide a target race
time based on your current state of fitness (Viewing Your Predicted Race Times, page 59).
HRV stress test: The heart rate variability (HRV) stress test requires a Garmin chest heart rate monitor. The
watch records your heart rate variability while standing still for 3 minutes. It provides your overall stress level.
The scale is 1 to 100, and a lower score indicates a lower stress level (Heart Rate Variability and Stress Level,
page 60).
Performance condition: Your performance condition is a real-time assessment after 6 to 20 minutes of activity.
It can be added as a data field so you can view your performance condition during the rest of your activity. It
compares your real-time condition to your average fitness level (Performance Condition, page 60).
Functional threshold power (FTP): The watch uses your user profile information from the initial setup to
estimate your FTP. For a more accurate rating, you can conduct a guided test (Getting Your FTP Estimate,
page 61).
Lactate threshold: Lactate threshold requires a chest heart rate monitor. Lactate threshold is the point where
your muscles start to rapidly fatigue. Your watch measures your lactate threshold level using heart rate data
and pace (Lactate Threshold, page 62).
Stamina: The watch uses your VO2 max. estimate and heart rate data to provide real-time stamina estimates. It
can be added as a data screen so you can view your potential and current stamina during your activity
(Viewing Your Real-Time Stamina, page 63).
Appearance 57
About VO2 Max. Estimates
VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram of body
weight at your maximum performance. In simple terms, VO2 max. is an indication of athletic performance and
should increase as your level of fitness improves. The D2 Mach 1 device requires wrist-based heart rate or a
compatible chest heart rate monitor to display your VO2 max. estimate. The device has separate VO2 max.
estimates for running and cycling. You must run either outside with GPS or ride with a compatible power meter
at a moderate level of intensity for several minutes to get an accurate VO2 max. estimate.
On the device, your VO2 max. estimate appears as a number, description, and position on the color gauge. On
your Garmin Connect account, you can view additional details about your VO2 max. estimate, such as where it
ranks for your age and gender.

Getting Your VO2 Max. Estimate for Running
This feature requires wrist-based heart rate or a compatible chest heart rate monitor. If you are using a chest
heart rate monitor, you must put it on and pair it with your watch (Pairing Your Wireless Sensors, page 80).
For the most accurate estimate, complete the user profile setup (Setting Up Your User Profile, page 95), and set
your maximum heart rate (Setting Your Heart Rate Zones, page 96). The estimate may seem inaccurate at first.
The watch requires a few runs to learn about your running performance. 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 (Activities
and App Settings, page 33).
1 Start a running activity.
2 Run for at least 10 minutes outdoors.
3 After your run, select Save.
4 Press UP or DOWN to scroll through the performance measurements.

Getting Your VO2 Max. Estimate for Cycling
This feature requires a power meter and wrist-based heart rate or a compatible chest heart rate monitor. The
power meter must be paired with your watch (Pairing Your Wireless Sensors, page 80). If you are using a chest
heart rate monitor, you must put it on and pair it with your watch.
For the most accurate estimate, complete the user profile setup (Setting Up Your User Profile, page 95) and set
your maximum heart rate (Setting Your Heart Rate Zones, page 96). The estimate may seem inaccurate at first.
The watch requires a few rides to learn about your cycling performance.
1 Start a cycling activity.
2 Ride at a steady, high intensity for at least 20 minutes.
3 After your ride, select Save.
4 Press UP or DOWN to scroll through the performance measurements.
Viewing Your Fitness Age
Your fitness age gives you an idea of how your fitness compares with a person of the same gender. Your watch
uses information, such as your age, body mass index (BMI), resting heart rate data, and vigorous activity history
to provide a fitness age. If you have a Garmin Index
™

Heart Rate Variability and Stress Level
Stress level is the result of a three-minute test performed while standing still, where the D2 Mach 1 device
analyzes heart rate variability to determine your overall stress. Training, sleep, nutrition, and general life stress
all impact how a runner performs. The stress level range is from 1 to 100, where 1 is a very low stress state and
100 is a very high stress state. Knowing your stress level can help you decide if your body is ready for a tough
training run or yoga.
Viewing Your Heart Rate Variability and Stress Level
This feature requires a Garmin chest heart rate monitor. Before you can view your heart rate variability (HRV)
stress level, you must put on a heart rate monitor and pair it with your device (Pairing Your Wireless Sensors,
page 80).
TIP: Garmin recommends that you measure your stress level at approximately the same time and under the
same conditions every day.

Performance Condition
As you complete your activity, such as running or cycling, the performance condition feature analyzes your pace,
heart rate, and heart rate variability to make a real-time assessment of your ability to perform compared to your
average fitness level. It is approximately your real-time percentage deviation from your baseline VO2 max.
estimate.
Performance condition values range from -20 to +20. After the first 6 to 20 minutes of your activity, the device
displays your performance condition score. For example, a score of +5 means that you are rested, fresh, and
capable of a good run or ride. You can add performance condition as a data field to one of your training screens
to monitor your ability throughout the activity. Performance condition can also be an indicator of fatigue level,
especially at the end of a long training run or ride.
NOTE: The device requires a few runs or rides with a heart rate monitor to get an accurate VO2 max. estimate
and learn about your running or riding ability (About VO2 Max. Estimates, page 58).

Lactate Threshold
Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the bloodstream.
In running, it is the estimated level of effort or pace. 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 10k 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, page 96). You can turn on the Auto Detection feature to automatically record your
lactate threshold during an activity.
Performing a Guided Test to Determine Your Lactate Threshold
This feature requires a Garmin chest heart rate monitor. Before you can perform the guided test, you must put
on a heart rate monitor and pair it with your device (Pairing Your Wireless Sensors, page 80).
The device uses your user profile information from the initial setup and your VO2 max. estimate to estimate
your lactate threshold. The device will automatically detect your lactate threshold during runs at a steady, high
intensity with heart rate.
TIP: The device requires a few runs with a chest heart rate monitor to get an accurate maximum heart rate value
and VO2 max. estimate. If you are having trouble getting a lactate threshold estimate, try manually lowering
your maximum heart rate value.

Training Status
These measurements are estimates that can help you track and understand your training activities. The
measurements require a few activities using wrist-based heart rate or a compatible chest heart rate monitor.
Cycling performance measurements require a heart rate monitor and a power meter.
These estimates are provided and supported by Firstbeat Analytics. For more information, go to garmin.com
/performance-data/running.
NOTE: The estimates may seem inaccurate at first. The watch requires you to complete a few activities to learn
about your performance.
Training status: Training status shows you how your training affects your fitness and performance. Your
training status is based on changes to your training load and VO2 max. 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, page 58). Your watch displays
heat and altitude corrected VO2 max. values when you are acclimating to high heat environments or high
altitude (Heat and Altitude Performance Acclimation, page 65).
Training load: Training load is the sum of your excess post-exercise oxygen consumption (EPOC) over the last 7
days. EPOC is an estimate of how much energy it takes for your body to recover after exercise (Training Load,
page 65).
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, page 66).
Recovery time: The recovery time displays how much time remains before you are fully recovered and ready for
the next hard workout (Recovery Time, page 67).
64 Appearance
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 training load and VO2 max. over an extended time period. You can use your training
status to help plan future training and continue improving your fitness level.
Peaking: Peaking means that 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.
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.
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 you should pay attention to your overall health including stress, nutrition, and rest.
Detraining: Detraining occurs when you are training much less than usual for a week or more, and it is affecting
your fitness level. You can try increasing your training load to see improvement.
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.
No Status: The device needs one or two weeks of training history, including activities with VO2 max. results
from running or cycling, to determine your training status.
Tips for Getting Your Training Status
The training status feature depends on updated assessments of your fitness level, including at least two VO2
max. measurements per week. Your VO2 max. estimate is updated after outdoor runs or rides with power during
which your heart rate reached at least 70% of your maximum heart rate for several minutes. 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 (Activities and App Settings, page 33).
To get the most out of the training status feature, you can try these tips.
• At least two times 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 device for one week, your training status should be available.
• Record all of your fitness activities on this device, or enable the Physio TrueUp feature, allowing your device
to learn about your performance (Syncing Activities and Performance Measurements, page 112).
Heat and Altitude Performance Acclimation
Environmental factors such as high temperature and altitude impact your training and performance. For
example, high altitude training can have a positive impact on your fitness, but you may notice a temporary VO2
max. decline while exposed to high altitudes. Your D2 Mach 1 watch provides acclimation notifications and
corrections to your VO2 max. estimate and training status when the temperature is above 22ºC (72ºF) and when
the altitude is above 800 m (2625 ft.). You can keep track of your heat and altitude acclimation in the training
status glance.
NOTE: The heat acclimation feature is available only for GPS activities and requires weather data from your
connected phone.
Training Load
Training load is a measurement of your training volume over the last seven days. It is the sum of your excess
post-exercise oxygen consumption (EPOC) measurements for the last seven days. The gauge indicates whether
your current load is low, high, or within the optimal range to maintain or improve your fitness level. The optimal
range is determined based on your individual fitness level and training history. The range adjusts as your
training time and intensity increase or decrease.
Appearance 65
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 training load is lower than optimal in all intensity categories. Try increasing the duration or
frequency of your workouts.
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 training load is higher than optimal, and you should consider scaling back the duration and
frequency of your workouts.

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, page 66). 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 sec) 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.

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.
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 140 bpm. 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.

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, page 97) 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.

132 Appendix
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.
Color Zone
Red Orange Green Orange Red
Symmetry Poor Fair Good Fair Poor

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.
Appendix 133
Vertical Oscillation and Vertical Ratio Data
The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and
whether it is positioned at the chest (HRM-Pro, HRM-Run
