UTMB OCC Route
The OCC begins in Orsières in Switzerland and finishes in Chamonix. The route offers up breathtaking views of the valley and the peaks of the eastern flanks of Mont Blanc.
Runners will see hanging glaciers and polished rocks, a true spectacle as they make their way through nature before reaching Campex and the final part of the course.
Facts, Tips & FAQ
The course contains 3,500 metres of ascension and is 55km long. Competitors must complete the course in a time of 14 hours 30 minutes with a maximum start list of 1,200 runners.
On course there will be five aid stations at 7km, 23km, 33km, 44km and 48km.
Competitors must provide a specific medical certificate in French in order to take part. The entry fee to take part in the OCC is €115 (£98).
Runners using poles must do so from the start and carry them for the whole race. No poles are authorised in the spare bags.
There are some areas of the course where, for safety or environmental reasons, poles are forbidden. These areas are marked by specific signs.
How to qualify and enter for UTMB OCC
The popularity of the UTMB races makes them increasingly difficult to enter. All runners who want to qualify have to do so through a lottery. Previously, entry to the lottery came through a points system with runners securing points from competing in UTMB affiliated races. But from 2023 onwards that system is changing with entry to the lottery requiring runners to have at least one Running Stone which they have acquired in the previous two years. Runners can collect running stones by competing in one of the UTMB World Series races.
Runners also need to have a valid UTMB Index in the category corresponding to the race. In the case of the OCC runners need a valid and up to date UTMB® Index in the 20K, 50K, 100K or 100M category
