Tool

GPX viewer with climbs

Drop a GPX or FIT file here: you get the elevation profile coloured by gradient, every climb with its category and how long it takes at your power. The file stays on your device.

Ride the route indoors

Load the same file into rampida and ride it in 3D on your smart trainer – in the browser, free during the beta.

FAQ

Is my GPX file uploaded?

No. The file is only read in your browser and never sent anywhere.

Which files work?

GPX from Komoot, Strava, Garmin Connect, Ride with GPS and others, plus FIT and FIT.GZ from your bike computer.

How are the climbs categorised?

Like in the grand tours, by length × gradient: category 4 to HC, from 500 m length and 3 % gradient.

How accurate is the ride time?

It assumes steady power without wind or drafting, with rolling and air resistance as in the app. Outdoors, wind, descents and stops also matter.
