About
The 50K World Series Final. 60km from Orsières through Swiss alpine terrain to Chamonix, crossing the Franco-Swiss border at the iconic Col de Balme. Launched in 2012 as part of UTMB week, the OCC is the proving ground for mid-distance ultra talent — elite runners competing at altitude before finishing under the same arch in the heart of Chamonix as their UTMB counterparts.
