the device may damage the product and will void the warranty.
NOTE: The device cannot record wrist heart rate data while
swimming.
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
device 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.

as dishwashing liquid.
NOTE: Using too much detergent may damage the heart rate
monitor.
Do not put the heart rate monitor in a washing machine or
dryer.
When drying the heart rate monitor, hang it up or lay it flat.
Running Dynamics
You can use your compatible D2 device paired with the
HRM-Run
accessory or other running dynamics accessory to
provide real-time feedback about your running form. If your D2
device was packaged with the HRM-Run accessory, the devices
are already paired.
The running dynamics accessory has an accelerometer that
measures torso movement in order to calculate six running
metrics.
Cadence: Cadence is the number of steps per minute. It
displays the total steps (right and left combined).
Vertical oscillation: Vertical oscillation is your bounce while
running. It displays the vertical motion of your torso,
measured in centimeters.
Ground contact time: Ground contact time is the amount of
time in each step that you spend on the ground while
running. It is measured in milliseconds.
NOTE: Ground contact time and balance are not available
while walking.
Ground contact time balance: Ground contact time balance
displays the left/right balance of your ground contact time
while running. It displays a percentage. For example, 53.2
with an arrow pointing left or right.
Stride length: Stride length is the length of your stride from one
footfall to the next. It is measured in meters.
Vertical ratio: Vertical ratio is the ratio of vertical oscillation to
stride length. It displays a percentage. A lower number
typically indicates better running form.
Training with Running Dynamics
Before you can view running dynamics, you must put on a
running dynamics accessory, such as the HRM-Run accessory,
and pair it with your device (Pairing ANT+ Sensors, page 29). If
your D2 Charlie was packaged with the accessory, the devices
are already paired, and the D2 Charlie is set to display running
dynamics data screens.

Select UP or DOWN to open a running dynamics screen to
view your metrics.
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
8 Heart Rate Features
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 www.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.
Color Zone Percentile in Zone Cadence Range Ground Contact Time Range
Purple >95 >183 spm <218 ms
Blue 70–95 174–183 spm 218–248 ms
Green 30–69 164–173 spm 249–277 ms
Orange 5–29 153–163 spm 278–308 ms
Red <5 <153 spm >308 ms
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
Percent of Other Runners 5% 25% 40% 25% 5%
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 color 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.
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-Tri
or HRM-Run accessories) or at the waist (Running Dynamics Pod accessory).
Color Zone Percentile in Zone Vertical Oscillation Range at
Chest
Vertical Oscillation Range at
Waist
Vertical Ratio at Chest Vertical Ratio at Waist
Purple >95 <6.4 cm <6.8 cm <6.1% <6.5%
Blue 70–95 6.4–8.1 cm 6.8–8.9 cm 6.1–7.4% 6.5–8.3%
Green 30–69 8.2–9.7 cm 9.0–10.9 cm 7.5–8.6% 8.4–10.0%

Red <5 >11.5 cm >13.0 cm >10.1% >11.9%
Tips for Missing Running Dynamics Data
If running dynamics data does not appear, you can try these
tips.
Make sure you have a running dynamics accessory, such as
the HRM-Run accessory.
Accessories with running dynamics have on the front of the
module.
Pair the running dynamics accessory with your D2 device
again, according to the instructions.
If the running dynamics data display shows only zeros, make
sure the accessory is worn right-side up.
NOTE: Ground contact time and balance appears only while
running. It is not calculated while walking.
Performance Measurements
These performance measurements require a few activities using
wrist-based heart rate or a compatible chest heart rate monitor.
The measurements are estimates that can help you track and
understand your training activities and race performances.
These estimates are provided and supported by Firstbeat. For
more information, go to www.garmin.com/physio.
NOTE: The estimates may seem inaccurate at first. The device
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.
Recovery time: The recovery time displays how much time
remains before you are fully recovered and ready for the next
hard workout.
Training load: Training load is the sum of your excess post-
exercise oxygen consumption (EPOC) over the last 7 days.
Heart Rate Features 9
EPOC is an estimate of how much energy it takes for your
body to recover after exercise.
Predicted race times: Your device uses the VO2 max. estimate
and published data sources to provide a target race time
based on your current state of fitness. This projection also
presumes you have completed the proper training for the
race.
HRV stress test: The HRV (heart rate variability) stress test
requires a Garmin chest heart rate monitor. The device
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.
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.
Functional threshold power (FTP): The device uses your user
profile information from the initial setup to estimate your FTP.
For a more accurate rating, you can conduct a guided test.
Lactate threshold: Lactate threshold requires a chest heart rate
monitor. Lactate threshold is the point where your muscles
start to rapidly fatigue. Your device measures your lactate
threshold level using heart rate data and pace.
Turning Off Performance Notifications
Performance notifications are turned on by default. Some
performance notifications are alerts that appear upon completion
of your activity. Some performance notifications appear during

Training Status
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
To get the most out of the training status feature, you can try
these tips.
Run outdoors with heart rate at least two times per week, or
ride with heart rate and power at least two times per week.
After using the device for one week, your training status
should be available.
Record all of your fitness activities on this device, allowing it
to learn about your performance.
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 Charlie 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.
Your VO2 max. estimate appears as a number and position on
the color gauge.

NOTE: From the watch face, you can select UP or DOWN to
view the performance widget, and select to scroll through
the performance measurements to view your recovery time.
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. You
can save or discard the activity after this value appears.
Training Load
Training load is a measurement of your training volume over the
last seven days. It is the sum of your 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.
Viewing Your Predicted Race Times
For the most accurate estimate, complete the user profile setup
(Setting Up Your User Profile, page 13), and set your
maximum heart rate (Setting Your Heart Rate Zones, page 13).
Your device uses the VO2 max. estimate (About VO2 Max.
Estimates, page 10) and published data sources to provide a
target race time based on your current state of fitness. This
projection also presumes you have completed the proper
training for the race.
NOTE: The projections may seem inaccurate at first. The device
requires a few runs to learn about your running performance.

aerobic and anaerobic fitness. Training Effect accumulates
during the activity. As the activity progresses, the Training Effect
value increases, telling you how the activity has improved your
fitness. Training Effect is determined by your user profile
information, heart rate, duration, and intensity of your activity.
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 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.
It is important to know that your Training Effect numbers (from
0.0 to 5.0) may seem abnormally high during your first few
activities. It takes several activities for the device to learn your
aerobic and anaerobic fitness.
You can add Training Effect as a data field to one of your
training screens to monitor your numbers throughout the activity.

Heart Rate Variability and Stress Level
Stress level is the result of a three-minute test performed while
standing still, where the D2 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 ANT+ Sensors, page 29). If your D2 Charlie device
was packaged with a heart rate monitor, the devices are already
paired.
TIP: Garmin recommends that you measure your stress level at
approximately the same time and under the same conditions
every day.

Stand still, and rest for 3 minutes.
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 10).
Viewing Your Performance Condition
This feature requires wrist-based heart rate or a compatible
chest heart rate monitor.
1
Add Perform. Cond. to a data screen (Customizing the Data
Screens, page 24).
2
Go for a run or ride.
After 6 to 20 minutes, your performance condition appears.
3
Scroll to the data screen to view your performance condition
throughout the run or ride.
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 13).
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 ANT+ Sensors,
page 29). You must also have a VO2 max. estimate from a
previous run (About VO2 Max. Estimates, page 10).
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.

6
After you complete the guided test, stop the timer and save
the activity.
If this is your first lactate threshold estimate, the device
prompts you to update your heart rate zones based on your
lactate threshold heart rate. For each additional lactate
threshold estimate, the device prompts you to accept or
decline the estimate.
Getting Your FTP Estimate
Before you can get your functional threshold power (FTP)
estimate, you must pair a chest heart rate monitor and power
meter with your device (Pairing ANT+ Sensors, page 29), and
you must get your VO2 max. estimate (Getting Your VO2 Max.
Estimate for Cycling, page 11).
The device uses your user profile information from the initial
setup and your VO2 max. estimate to estimate your FTP. The
device will automatically detect your FTP during rides at a
steady, high intensity with heart rate and power.

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.
Knowing your heart rate zones can prevent you from
overtraining and can decrease your risk of injury.
If you know your maximum heart rate, you can use the table
(Heart Rate Zone Calculations, page 14) 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.
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.
Setting Your Heart Rate Zones
The device uses your user profile information from the initial
setup to determine your default heart rate zones. You can set
separate heart rate zones for sport profiles, such as running,
cycling, and swimming. For the most accurate calorie data
during your activity, set your maximum heart rate. You can also

, and 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 device 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). You
can work toward achieving your weekly intensity minutes goal by
participating in at least 10 consecutive minutes of moderate to
vigorous intensity activities. The device adds the amount of
moderate activity minutes with the amount of vigorous activity
minutes. Your total vigorous intensity minutes are doubled when
