Power Guide
You can create and use a power strategy to plan your effort on a course. Your Edge 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 a Power Guide, page5). 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, page45). After the
devices are paired, you can customize the optional data fields (Data Fields, page75).

Before you can create a power guide, you must pair a power meter with your device (Pairing Your Wireless
Sensors, page45).

My Stats
The Edge 840 bike computer can track your personal statistics and calculate performance measurements.
Performance measurements require a compatible heart rate monitor, power meter, or smart trainer.
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 www.garmin
.com/performance-data.
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. Your device displays heat and altitude corrected VO2 max.
values when you are acclimating to high heat environments or high altitude.
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 focus: Your device 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 device displays your load distribution over the last 4 weeks.
Recovery time: The recovery time displays how much time remains before you are fully recovered and ready for
the next hard workout.
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.
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.
Power curve: The power curve displays your sustained power output over time. You can view your power curve
for the previous month, three months, or twelve months.
My Stats 13
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 device needs you to record multiple activities over two weeks 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. Your VO2 max. estimate is updated after both indoor and outdoor rides with
power during which your heart rate reached at least 70% of your maximum heart rate for several minutes.
To get the most out of the training status feature, you can try these tips.
At least one time per week, ride 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 your primary training device, allowing your device to learn about your
performance (Syncing Activities and Performance Measurements, page23).
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. VO2 max. estimates are provided and supported by Firstbeat.
You can use your Garmin device paired with a compatible heart rate monitor and power meter to display your
cycling VO2 max. estimate.

Getting Your VO2 Max. Estimate
Before you can view your VO2 max. estimate, you must put on the heart rate monitor, install the power meter,
and pair them with your device (Pairing Your Wireless Sensors, page45). If your device was packaged with a
heart rate monitor, the device and sensor are already paired. For the most accurate estimate, complete the user
profile setup (Setting Up Your User Profile, page52), and set your maximum heart rate (Setting Your Heart Rate
Zones, page42).
NOTE: The estimate may seem inaccurate at first. The device requires a few rides to learn about your cycling
performance.

Tips for Cycling VO2 Max. Estimates
The success and accuracy of the VO2 max. calculation improves when your ride is a sustained and moderately
hard effort, and where heart rate and power are not highly variable.
Before your ride, check that your device, heart rate monitor, and power meter are functioning properly, paired,
and have good battery life.
During your 20 minute ride, maintain your heart rate at greater than 70% of your maximum heart rate.
During your 20 minute ride, maintain a fairly constant power output.
Avoid rolling terrain.
Avoid riding in groups where there is a lot of drafting.
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 Edge 840 device 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.).
NOTE: The heat acclimation feature is available only for GPS activities and requires weather data from your
connected phone.
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.
Viewing Your Acute Load
Before you can view your acute load estimate, you must put on the heart rate monitor, install the power meter,
and pair them with your device (Pairing Your Wireless Sensors, page45).
If your device was packaged with a heart rate monitor, the device and sensor are already paired. For the
most accurate estimate, complete the user profile setup (Setting Up Your User Profile, page52), and set your
maximum heart rate (Setting Your Heart Rate Zones, page42).

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.
Viewing Cycling Ability
Before you can view your cycling ability, you must have a 7-day training history, VO2 max. data recorded in your
user profile (About VO2 Max. Estimates, page14), and power curve data from a paired power meter (Viewing
Your Power Curve, page23).
Cycling ability is a measurement of your performance across three categories: aerobic endurance, aerobic
capacity, and anaerobic capacity. Cycling ability includes your current rider type, such as climber. Information
you enter in your user profile, such as body weight, also helps determine your rider type (Setting Up Your User
Profile, page52).

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17). 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.

The device uses your user profile information from the initial setup to determine your heart rate zones. You can
manually adjust the heart rate zones according to your fitness goals (Fitness Goals, page42). For the most
accurate calorie data during your activity, you should set your maximum heart rate, resting heart rate, and heart
rate zones.

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84) 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.
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.

5Take a 15minute test ride and inspect the sensor and bands to ensure there is no evidence of damage.
About the Speed and Cadence Sensors
Cadence data from the cadence sensor is always recorded. If no speed and cadence sensors are paired with the
device, GPS data is used to calculate the speed and distance.
Cadence is your rate of pedaling or “spinning” measured by the number of revolutions of the crank arm per
minute (rpm).
Data Averaging for Cadence or Power
The non-zero data-averaging setting is available if you are training with an optional cadence sensor or power
meter. The default setting excludes zero values that occur when you are not pedaling.
You can change the value of this setting (Data Recording Settings, page59).
44 Wireless Sensors
Pairing Your Wireless Sensors
Before you can pair, you must put on the heart rate monitor or install the sensor.
The first time you connect a wireless sensor to your device using ANT+ or Bluetooth technology, you must pair
the device and sensor. If the sensor has both ANT+ and Bluetooth technology, Garmin recommends that you
pair using ANT+ technology. After they are paired, the Edge bike computer connects to the sensor automatically
when you start an activity and the sensor is active and within range.
NOTE: If your device was packaged with a sensor, they are already paired.

For calibration instructions specific to your power meter, see the manufacturer's instructions.
1Select > Sensors.
2Select your power meter.
3Select Calibrate.
4Keep your power meter active by pedaling until the message appears.
5Follow the on-screen instructions.
Pedal-Based Power
Rally measures pedal-based power.
Rally measures the force you apply a few hundred times every second. Rally also measures your cadence or
rotational pedaling speed. By measuring the force, the direction of force, the rotation of the crank arm, and time,
Rally can determine power (watts). Because Rally independently measures left and right leg power, it reports
your left-right power balance.
NOTE: The single-sensing Rally system does not provide left-right power balance.
Cycling Dynamics
Cycling dynamics metrics measure how you apply power throughout the pedal stroke, and where you apply
power on the pedal, allowing you to understand your particular way of riding. Understanding how and where you
produce power allows you to train more efficiently and evaluate your bike fit.
NOTE: You must have a compatible, dual sensing power meter connected using ANT+ technology to use cycling
dynamics metrics.
For more information, go to www.garmin.com/performance-data.
