Share in the adventure of the OCC race of the UTMB® Mont-Blanc 2021 whether you are in Chamonix or not. #UTMB4YOU
We invite you to join us and take part in the Virtual Race to live your own OCC experience. To become a finisher, you must complete 35 km in no more than 2 runs with 400 m of negative elevation gain from wherever you are in the world.

About OCC:

To transport yourself to the OCC, you have to first imagine Switzerland and the canton of Val d'Entremont, where Orsières, the start of the race, is located. This valley offers unique landscapes: last spurs and ultimate needles of the eastern flank of the Mont-Blanc drawing the Franco-Swiss border, glaciers hanging on the polished rocks, fiery torrents... The OCC allows you to experience the incredible natural world and a special atmosphere before reaching Champex and the last part of the UTMB® or CCC route, which is also magical.

Rules of Virtual Race

To become a Finisher, you must run 35km with 400 of gain elevation. The Virtual Race must be completed by walking/running outdoors. The Virtual Race has to be completed in no more than two runs.


The ranking is calculated on the overall timing based on the GPX tracks provided between the first run (start) and the last run (finish). Thus, runners who choose to complete the Virtual Race in one single run will be ahead of those who have complete it in several runs. In the event of a tie, the activity time (= time in motion) will be taken into consideration.
