INTRODUCTION
Congratulations on your new Polar Grit X!
The Polar Grit X outdoor watch is a lightweight but durable multisport watch for trail running, mountain
biking, hiking – for all your outdoor sports.
Take your training to new highs and optimize your performance with Polar Grit X, the outdoor watch
designed for the moments when the road is not enough and new goals are waiting off the beaten track.
It comes with built-in GPS, compass and altimeter, and Polar’s unique training features.
With Polar Grit X and Hill Splitter™, you’ll know how you performed on the uphill and downhill sections
of your session. You get detailed data about the elevation profile of your training session, and you’ll be
able to compare hill stats between different sessions. Hill Splitter™ automatically detects all uphills and
downhills by using your speed, distance and altitude data. It shows you detailed insights into your
performance, such as distance, speed, ascent and descent, for every detected hill on your course.
Stay energized throughout your session with the new FuelWise™ fueling assistant. FuelWise™ reminds
you to refuel and helps you maintain adequate energy levels during your long sessions. See how your
body uses different energy sources during a training session. Polar Grit X divides your energy usage into
carbs, proteins and fats.
Stay on the right path with Polar Grit X and Komoot. When you’re pushing your limits off the beaten
track, knowing your way is vital. With Polar Grit X, you can import routes from Polar Flow or from
Komoot and follow the real-time route guidance on your watch. When you import your route directly
from Komoot, you get detailed turn-by-turn route guidance.
Additional feature highlights include:
l Advanced wrist-based heart rate with the Precision Prime™ sensor fusion technology.
l Detailed weather data straight on your watch. Check current weather info and a 2-day forecast
straight on your watch.
l The FitSpark™ training guide makes sure you’re prepared for your pursuit to conquer the trails
with ready-made daily workouts that match your recovery, readiness and training history.
l See how well you recover from your day during the night with Nightly Recharge™.
l Get a more comprehensive insight into the intensity of your running sessions with Running
power.
l The Swimming metrics feature on Polar Grit X automatically detects your heart rate, swimming
style, distance, pace, strokes and rest times. Distance and strokes get tracked also in open water
swimming.
