Step 1 of 4

Upload your run

Export the run from your watch or running app and drop the file here. The time that counts is the one your device recorded, not one you type in.

  • GPX, FIT or TCX from any GPS watch or running app
  • We never store your GPS track — only a fingerprint of the run
  • Only your name, city and time go on the public ledger

Drop your GPX, FIT or TCX file here

It's read in your browser first, then verified on our server.

How do I get the file?
  • Strava (website): open the activity, click the ⋯ menu, then Export GPX.
  • Garmin Connect: open the activity, click the gear icon, then Export Original (a .zip with the .fit file inside — unzip it first).
  • Other apps (Coros, Polar, Suunto, Apple Watch apps): look for Export or Share file on the activity.
