About This Route
The OCC packs UTMB week into a single alpine day: 56 kilometres and 3,500 metres of climbing from Orsières in Switzerland through Champex-Lac, over Bovine, past Trient and Vallorcine and up to La Flégère before the drop to the finish arch in Chamonix — the same finish line, the same crowds, the same massif as the big loop.
For many runners the OCC is a first taste of the Mont Blanc trails, for others a world-championship distance raced flat out. Either way it's a race worth keeping. Our 3D printed terrain model renders the Swiss and French flanks of the massif with your route traced across them.
