Frequently asked questions
Everything you need to know about the 3D route viewer.
How do I view a GPX route in 3D?
Drag your .gpx file onto the upload area above. Within seconds the route appears on a 3D map with real terrain, ready for you to hit play, navigate and analyze every metric.
Which files can I open in the Route Explorer?
We accept .fit files (Garmin, Wahoo, Coros, Suunto), .gpx files (Strava, Polar, Amazfit, Zepp, Apple Health) and .geojson. Anything with GPS coordinates works.
Do I need an account to use it?
No. The Route Explorer is completely free and works without signing up. Create an account only if you want to sync your Amazfit/Zepp activities automatically and get history, gamification and dashboards.
Which metrics does the viewer show?
Distance, duration, average and best pace, average/min/max heart rate, elevation gain and loss, cadence, estimated calories, VAM, kilometer-by-kilometer splits, heart rate zones, pace zones, and synced charts of pace, heart rate, elevation and cadence along the route.
Can I watch the route as a video?
Yes. Hit Play and the route animates in real time with a dynamic 3D camera. Every layer (pace, heart rate, elevation) appears at once over the real terrain.
Does it work for running, cycling, trail and hiking?
Yes — any GPS activity works: road running, trail running, road cycling, MTB, walking, trekking or skiing. The metrics adapt to the activity type detected in the file.
