GPX viewer

Open a route file and it goes on the map, with the height profile underneath. If the file has times you'll also see how long it took, and how much of that you spent moving.

Your files stay on your device. Nothing is uploaded.

Tidy it and save it again

Most recordings start with the drive to the car park. Drag the handle at the start of the height profile past it and those miles come off the total. Stray points, where the GPS jumped off somewhere and came straight back, show in red and go with one press. Then save it as a GPX or another type. The file you opened stays as it was.

What a GPX file is

It's a GPS recording in a plain text file. Each point is a line like these, with where you were and usually your height and the time. Nearly every watch and sports app can save one, which is why it's the format to ask for.

Where to get a GPX

The export button is a bit hidden in most apps. This is where to find it.

Questions

Is my file uploaded?

No. Your browser opens it and draws it on this page, and it stays on your device. The only thing that sends a route anywhere is the button to make a film.

Which files can it open?

GPX, KML, KMZ, FIT, TCX and GeoJSON. A zip from Garmin Connect's Export Original opens as it is.

Why is the climb different from Strava or Garmin?

GPS heights wobble by a few metres and every app smooths them its own way. We only count a rise once it's more than 4 metres. Strava and Garmin can also check heights against a map of the ground, which we don't do here.

What counts as moving time?

Any time you were going faster than about 1.5 km/h. A long lunch doesn't count, and nor does waiting at the lights.

What are stray points?

Points where the GPS jumped away from the line and came straight back. It can also be a first point miles off because the watch hadn't found the satellites yet. They add distance you never did.

Is it still there if I close the page?

Yes, on the same device and browser. The file and your cuts stay open until you press Start again.
