Steps
- Sign in to Polar Flow. Go to flow.polar.com and log in.
- Open Favorites. Click the Favorites icon in the top-right corner, then choose “Import route”.
- Upload your GPX. Drag in or browse to your .gpx (TCX also works, up to 25 MB), click “Import”, name the route and click “Import” again.
- Sync your watch. Sync the watch with Polar FlowSync or the Polar Flow app, depending on your model; the route is then available for route guidance on supported watches.
Quirks & limits
- Route guidance works on supported models such as Grit X / X Pro, Grit X2 / X2 Pro, Pacer Pro, Street X, Vantage V2, V3 and M3.
- Long routes are compressed: older models keep 500 waypoints, while Grit X2, Street X, Vantage V3 and M3 keep up to 1,500.
- Polar watches can also get routes from komoot, but that transfer needs komoot Premium.
