Komoot
Plan detailed routes on maps with komoot and transfer the routes to your watch for turn-by-turn route guidance on the go! Whether road cycling, hiking, bikepacking or mountain biking, komoot’s superior planning and navigation technology allows you to easily discover more of the great outdoors.
Create a komoot account if you don't have one. When you sign up for komoot, you get a free region to test all of their core features. Komoot recommends to unlock your home region as your free region. Then connect komoot to Polar Flow, and get your komoot routes on your watch. Every time you sync your watch your Flow routes sync back to komoot automatically.
If your Flow training routes are not transferred to komoot automatically, you need to disconnect and reconnect the connection from Flow settings.
