Aletsch Arena · UNESCO World Heritage
Start anywhere on the loop. Start any time you like — pick your weather, your daylight, your direction of attack. Complete one full loop back to your own starting point, upload the file, and the clock is yours.
Sign up with the tourist office and download the official course file. One registration covers the whole season and as many attempts as you want.
Start wherever you are, whenever conditions suit you. Record the whole thing on your watch and finish back at your own starting point.
Drop the file here. It is checked against the official course in a few seconds, and a valid loop goes straight onto the leaderboard.
Load the real course and everything on this page follows it — distance, ascent, the profile above, and every check. GPX, TCX or FIT. It stays in this browser; to ship it to everyone, replace course.gpx in the deployed folder.
One real submission and three simulated ones, so you can show every outcome without going for a run. Nico's is a genuine Strava export and behaves like a real file will.
Demo entries are placeholders. Results are filed against the course they were run on, so loading the real course hides them automatically.
