Polar Pacer Pro

Training Load Pro™

When you train, the different systems of your body become strained. Training Load Pro™ monitors this strain to provide you with detailed insights.

Training Load Pro™ gives you values for the load placed on both your cardiovascular and musculoskeletal system (Cardio Load and Muscle Load) after every session, and with Perceived Load you can rate how strained you feel - allowing you to see the immediate strain on your body, and monitor training induced strain over the long-term.

Learn more about Training Load Pro™

• Monitor how your training strains your body
• Understand your cardio & muscle loads
• Track loads by session, and over the long-term

Precision Prime™

Polar Precision Prime™ sensor fusion technology tracks your heart rate from the wrist. The innovation combines optical heart rate measurement with other sensor technologies to rule out motion artifacts that might disturb the heart rate signal and produce unreliable readings.

• Deeper light penetration into the skin
• Light detectors pick up returning light
• Accurate heart rate measurement

Walking Test

Walking Test is an uncomplicated test that you can perform regularly to estimate your aerobic fitness level based on your VO2max.

Walk at a brisk pace for 15 minutes along a flat route and the automatic calculation will factor in the distance you walk, your heart rate during the test, and your personal metrics: gender, age, height, and weight.

Global Navigation Satellite Systems

Train with the best positioning experience anywhere in the world.

The built-in GPS works together with GLONASS and Galileo global navigation satellite systems, and QZSS regional navigation satellite system for East Asia and Oceania to provide accurate speed, distance, and route data anywhere on the planet.

Assisted-GPS provides faster fixes and tells your watch the predicted positions of the satellites, making it possible to receive signals from them within seconds wherever you are, even under difficult conditions.

• Assisted-GPS for faster fix times
• Supports multiple satellite systems
• Accurate location, speed, and distance data

Back to Start

Get back to where you started.

Back to Start guides you to your starting point in the shortest distance possible (beeline) – displaying your bearings and an arrow pointing you in the right direction, as well as the direct distance between you and where you need to get to.

• Get back to your starting point
• Follow the arrow for directions
• See the distance you have left

Route & Elevation Profiles

With route and elevation profiles you can see the terrain you covered during your training session in Polar Flow as a detailed summary – with calculated slope angles for every ascent and descent of the recorded session.

• Automatic slope angle calculations
• Elevation profiles for training terrain
• Get detailed insights for the route you covered

Hill Splitter™

Hill Splitter™ automatically detects all uphills and downhills by using your GPS-based speed, distance, and barometric altitude data.

It shows you detailed insights into your performance, such as the distance you have traveled, the speed you covered it, and how much you climbed or descended on every detected hill during your session, automatically adapting to the terrain you are training on with every effort counted.

• Automatic uphill & downhill detection
• Get detailed climb and descent insights
• Track every effort on all terrains

Sleep Plus Stages™

Getting enough good-quality sleep is vital for your health and well-being. When you sleep, your body cycles through three sleep stages: light, deep, and REM.

Sleep Plus Stages™ automatically tracks the amount and quality of your sleep (Sleep Score), and lets you know how long you spent in each stage during the night.

Sleep tracking can help you understand your sleep behavior over the long-term, and also identify the factors in your day that may have a negative impact on your sleep.

Learn more about Sleep Plus Stages™

• Automatically track the quality of your sleep
• See your Sleep Score at a glance
• Learn how factors affect your sleep behavior

SleepWise™

Learn how your sleep behavior affects your day’s energy and alertness levels.
With SleepWise™, you get daytime alertness insights that help you perfect a bedtime routine so you can face your daily challenges sharp and ready.

By factoring in your sleep amount, quality, and your body’s internal circadian rhythm, SleepWise™ lets you know how the effects of sleep accumulate over time, making the impact of sleep debt and irregular sleep-wake rhythm visible.

• See your daytime alertness forecast
• Learn how your sleep affects your day
• Estimate your optimal sleep time

Serene™

Relax your body and calm your mind with Serene™ guided breathing exercise.

Deep breathing is known to be an easy and efficient way to manage stress, build resilience and improve focus. Serene™ guides you to breathe at a slow, regular rhythm to synchronize your heart rate with your rate of breathing – six breaths per minute; which is the optimal breathing rate for shutting down your body's stress response.

Learn more about Serene™

• Improve your well-being, sleep, and stress resilience
• Easy, relaxing guided breathing exercises
• Sync your heart rate and breathing rate

Nightly Recharge™

Nightly Recharge™ is an automatic overnight recovery measurement that shows you how well you recover from the demands of your day. It helps you make the optimal choices in your everyday life to maintain overall well-being and reach your training or fitness goals.

Your Nightly Recharge™ status is based on two components: how you slept (Sleep Charge), and how well your autonomic nervous system calmed down during the early hours of your sleep (ANS Charge).

Learn more about Nightly Recharge™

• Automatic overnight recovery measurement
• Get tips to improve sleep and training
• Based on your sleep, and ANS status

Running Power

Whereas heart rate measures your internal load as you run (cardio effort required), Running Power monitors your external work rate in watts as you run (mechanical output from your muscles).

This is an extremely useful tool for sprints and short intervals because it responds to intensity changes almost instantly.

Because Running Power responds quickly to intensity changes, has a high dynamic range, and takes into account changes in altitude, it’s perfect for interval training and running in hilly terrain.

By monitoring changes in your pace and altitude, you can use Running Power to maintain a steady level of effort during a steady-state workout in varying terrain, for example, running on a trail.

Running Index

After every run, you get a Running Index score based on the relationship between heart rate and speed. A single number to see your progress and compare to gender and age related aerobic fitness norms.

Because Running Index gives you an estimate of your maximal aerobic performance, it is a good predictor of your finish time for popular race distances, from 5k to marathon.

Learn more about Running Index

• See how efficient your running is.
• Monitor your progress with a single score.
• Predict how fast you can run a race

Training Targets

Plan your training sessions in advance with customized training targets and save them to your training diary. When it’s to break a sweat, your device will guide you throughout your scheduled session, so you can fully focus on your workout.

You can create interval workouts with heart rate, speed, or power targets, or set simple training goals, such as ‘burn 700 kcal cycling’ or ‘run 30 minutes.’ Your device will alert you when you need to slow down or speed up to make sure your training goes as planned.

Learn more about Training Targets

• Create your own training targets
• Get guidance and alerts for each session
• Analyze your training in Polar Flow

Running Power In Action

Because Running Power responds quickly to intensity changes, has a high dynamic range, and takes into account changes in altitude, it’s perfect for interval training and running in hilly terrain.

By monitoring changes in your pace and altitude, you can use Running Power to maintain a steady level of effort during a steady-state workout in varying terrain, for example, running on a trail.
