Training
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. Swolf is a measurement of swimming efficiency and, like
golf, a lower score is better.
Indoor Activities
The Forerunner device can be used for training indoors, such as
running on an indoor track or using a stationary bike. GPS is
turned off for indoor activities.
When running or walking with GPS turned off, speed, distance,
and cadence are calculated using the accelerometer in the
device. The accelerometer is self-calibrating. The accuracy of
the speed, distance, and cadence data improves after a few
outdoor runs or walks using GPS.
TIP: Holding the handrails of the treadmill reduces accuracy.
You can use an optional foot pod to record pace, distance, and
cadence.
When cycling with GPS turned off, speed and distance are not
available unless you have an optional sensor that sends speed
and distance data to the device (such as a speed or cadence
sensor).
Workouts
You can create custom workouts that include goals for each
workout step and for varied distances, times, and calories. You
can create workouts using Garmin Connect™ or select a training
plan that has built-in workouts from Garmin Connect, and
transfer them to your device.
You can schedule workouts using Garmin Connect. You can
plan workouts in advance and store them on your device.
About the Training Calendar
The training calendar on your device is an extension of the
training calendar or schedule you set up in Garmin Connect.
After you have added a few workouts to the Garmin Connect
calendar, you can send them to your device. All scheduled
workouts sent to the device appear in the training calendar list
by date. When you select a day in the training calendar, you can
view or do the workout. The scheduled workout stays on your
device whether you complete it or skip it. When you send
scheduled workouts from Garmin Connect, they overwrite the
existing training calendar.
Using Garmin Connect Training Plans
Before you can download and use a training plan, you must
have a Garmin Connect account (Garmin Connect, page 4).
You can browse your Garmin Connect account to find a training
plan, schedule workouts, and send them to your device.
1Connect the device to your computer.
2From your Garmin Connect account, select and schedule a
training plan.
3Review the training plan in your calendar.
4Select , and follow the on-screen instructions.
Interval Workouts
You can create interval workouts based on distance or time. The
device saves your custom interval workout until you create
another interval workout. You can use open intervals for track
workouts and when you are running a known distance.
Heart Rate Features
The Forerunner device has a wrist-based heart rate monitor and
is also compatible with ANT+® chest heart rate monitors. You
can view wrist-based heart rate data on the heart rate widget.
When both wrist-based heart rate and ANT+ heart rate data are
available, your device uses the ANT+ heart rate data. You must
have a heart rate monitor to use the features described in this
section.
Running Dynamics
You can use your compatible Forerunner device paired with the
HRM-Run™ accessory to provide real-time feedback about your
running form. If your Forerunner device was packaged with the
HRM-Run accessory, the devices are already paired.
The HRM-Run accessory has an accelerometer in the module
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 for each step.
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 is not available while walking.
Ground contact time balance: Ground contact time balance
displays the left/right balance of your ground contact time
Introduction 1
![](/img.php?id=3321969&img=bg6.png)
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.
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.
NOTE: The color gauge for ground contact time balance is different (Ground Contact Time Balance Data, page 2).
Go to www.garmin.com 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 Vertical Oscillation Range Vertical Ratio Ground Contact Time Range
Purple >95 >183 spm <6.4 cm <6.1% <218 ms
Blue 70–95 174–183 spm 6.4–8.1 cm 6.1–7.4% 218–248 ms
Green 30–69 164–173 spm 8.2–9.7 cm 7.5–8.6% 249–277 ms
Orange 5–29 153–163 spm 9.8–11.5 cm 8.7–10.1% 278–308 ms
Red <5 <153 spm >11.5 cm >10.1% >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.
Physiological Measurements
These physiological measurements require wrist-based heart
rate or a compatible 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.
NOTE: The estimates may seem inaccurate at first. The device
requires you to complete a few activities to learn about your
performance.
VO2 max.: Cycling VO2 max. requires a chest heart rate
monitor. VO2 max. is the maximum volume of oxygen (in
milliliters) you can consume per minute per kilogram of body
weight at your maximum performance.
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.
Recovery advisor: The recovery advisor displays how much
time remains before you are fully recovered and ready for the
next hard workout.
Stress score: Stress score requires a chest heart rate monitor.
Stress score measures 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.
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.
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. You can use your Garmin device
paired with a compatible heart rate monitor to display your
running VO2 max. estimate.
Your VO2 max. estimate appears as a number and position on
the color gauge.

VO2 max. data and analysis is provided with permission from
The Cooper Institute®. For more information, see the appendix
(VO2 Max. Standard Ratings, page 9), and go to
www.CooperInstitute.org.
Recovery Advisor
You can use your Garmin device with a heart rate monitor to
display how much time remains before you are fully recovered
and ready for the next hard workout.
Recovery time: The recovery time appears immediately
following an activity. The time counts down until it is optimal
for you to attempt another hard workout.
Recovery Heart Rate
If you are training with a 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.
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.
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 (getting your vo2 max cycling).
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 heart rate
zones).
Activity Tracking
Sleep Tracking
While you are sleeping, the device monitors your movement.
Sleep statistics include total hours of sleep, sleep levels, and
sleep movement. You can set your normal sleep hours in the
user settings on your Garmin Connect account. You can view
your sleep statistics on your Garmin Connect account.
Intensity Minutes
To improve your health, organizations such as the U.S. Centers
for Disease Control and Prevention, the American Heart
Association®, 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
added.
Earning Intensity Minutes
Your Forerunner device calculates intensity minutes by
comparing your heart rate data during an activity to your
average resting heart rate. If heart rate is turned off, the device
calculates moderate intensity minutes by analyzing your steps
per minute.
• Start a timed activity for the most accurate calculation of
intensity minutes.
• Exercise for at least 10 consecutive minutes at a moderate or
vigorous intensity level.

HRM-Swim™ Accessory
Sizing the Heart Rate Monitor
Before your first swim, take some time sizing the heart rate
monitor. It should be tight enough to stay in place when pushing
off the pool wall.
• Select a strap extender, and attach it to the elastic end of the
heart rate monitor.
The heart rate monitor comes with three extender straps to fit
different chest sizes.
TIP: The medium strap extender works for most shirt sizes
(from medium to extra-large).
• Put on the heart rate monitor backward to easily adjust the
slider on the strap extender.
• Put on the heart rate monitor forward to easily adjust the
slider on the heart rate monitor.
Putting On the Heart Rate Monitor
You should wear the heart rate monitor directly on your skin, just
below your sternum.
1Select a strap extender for the best fit.
2Wear the heart rate monitor with the Garmin logo facing right-
side up.
The hook À and loop Á connection should be on your right
side.
3Wrap the heart rate monitor around your chest, and connect
the strap hook to the loop.
NOTE: Make sure the care tag does not fold over.
4Tighten the heart rate monitor so it is snug around your
chest, but not restrictive.
After you put on the heart rate monitor, it is active, storing, and
sending data.
Tips for Using the HRM-Swim Accessory
• Adjust the tightness of the heart rate monitor and strap
extender if the heart rate monitor slides down your chest
when pushing off the pool wall.
• Stand up between intervals so that the heart rate monitor is
out of the water to see your heart rate data.
Caring for the Heart Rate Monitor
NOTICE
A buildup of sweat and salt on the strap can decrease the ability
of the heart rate monitor to report accurate data.
• Rinse the heart rate monitor after every use.
• Hand wash the heart rate monitor after every seven uses,
using a tiny amount of mild detergent, such 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.
HRM-Tri™ Accessory
The HRM-Swim section of this manual explains recording heart
rate during your swim (swimming in open water).
Pool Swimming
NOTICE
Hand wash the heart rate monitor after exposure to chlorine or
other pool chemicals. Prolonged exposure to these substances
can damage the heart rate monitor.
Navigation 5
![](/img.php?id=3321969&img=bga.png)
The HRM-Tri accessory is designed primarily for open water
swimming, but it can be used occasionally for pool swimming.
The heart rate monitor should be worn under a swim suit or
triathlon top during pool swimming. Otherwise, it may slide down
your chest when pushing off the pool wall.
Putting On the Heart Rate Monitor
You should wear the heart rate monitor directly on your skin, just
below your sternum. It should be snug enough to stay in place
during your activity.
1If necessary, attach the strap extender to the heart rate
monitor.
2Wet the electrodes À on the back of the heart rate monitor to
create a strong connection between your chest and the
transmitter.
3Wear the heart rate monitor with the Garmin logo facing right-
side up.
The loop Á and hook  connection should be on your right
side.
4Wrap the heart rate monitor around your chest, and connect
the strap hook to the loop.
NOTE: Make sure the care tag does not fold over.
After you put on the heart rate monitor, it is active and sending
data.
Data Storage
The heart rate monitor can store up to 20 hours of data in a
single activity. When the heart rate monitor memory is full, your
oldest data is overwritten.
You can start a timed activity on your paired Forerunner device,
and the heart rate monitor records your heart rate data even if
you move away from your device. For example, you can record
heart rate data during fitness activities or team sports where
watches cannot be worn. Your heart rate monitor automatically
sends your stored heart rate data to your Forerunner device
when you save your activity. Your heart rate monitor must be
active and within range (3 m) of the device while data is
uploaded.
Caring for the Heart Rate Monitor
NOTICE
A buildup of sweat and salt on the strap can decrease the ability
of the heart rate monitor to report accurate data.
• Rinse the heart rate monitor after every use.
• Hand wash the heart rate monitor after every seven uses or
one pool swim, using a tiny amount of mild detergent, such
as dishwashing liquid.

Your device is compatible with the foot pod. You can use the
foot pod to record pace and distance instead of using GPS when
you are training indoors or when your GPS signal is weak. The
foot pod is on standby and ready to send data (like the heart
rate monitor).
After 30 minutes of inactivity, the foot pod powers off to
conserve the battery. When the battery is low, a message
appears on your device. Approximately five hours of battery life
remain.
Foot Pod Calibration
The foot pod is self-calibrating. The accuracy of the speed and
distance data improves after a few outdoor runs using GPS.
Situational Awareness
Your Forerunner device can be used with the Varia Vision™
device, Varia™ smart bike lights, and rearview radar to improve
situational awareness. See the owner's manual for your Varia
device for more information.
NOTE: You may need to update the Forerunner software before
pairing Varia devices (Updating the Software, page 8).
Tips for Erratic Heart Rate Data
If the heart rate data is erratic or does not appear, you can try
these tips.
• Reapply water to the electrodes and contact patches (if
applicable).
• Tighten the strap on your chest.
• Warm up for 5 to 10 minutes.
• Follow the care instructions (Caring for the Heart Rate
Monitor, page 6).
• Wear a cotton shirt or thoroughly wet both sides of the strap.
Synthetic fabrics that rub or flap against the heart rate
monitor can create static electricity that interferes with heart
rate signals.
• Move away from sources that can interfere with your heart
rate monitor.
Sources of interference may include strong electromagnetic
fields, some 2.4 GHz wireless sensors, high-voltage power
lines, electric motors, ovens, microwave ovens, 2.4 GHz
cordless phones, and wireless LAN access points.
Customizing Your Device
Activity Profiles
Activity profiles are a collection of settings that optimize your
device based on how you are using it. For example, the settings
and data screens are different when you are using the device for
running than for riding your bike.
When you are using a profile and you change settings such as
data fields or alerts, the changes are saved automatically as part
of the profile.
Activity Settings
These settings allow you to customize your device based on
your training needs. For example, you can customize data
screens and enable alerts and training features.
Alerts
You can use alerts to train toward specific heart rate, pace, time,
distance, cadence, and calories goals and to set run/walk time
intervals.

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.
