The race
The RunThrough Ultra-Trail d'Orsières runs three distances — 50K (2990m gain), 25K (1190m gain) and the 15K Valley Explorer — on alpine trails linking Orsières, Champex-Lac and Sembrancher, following sections of the Tour du Mont Blanc route. The start is a five-minute walk from Orsières train station, making it straightforward to get there without a car. At 50K with 2990m of climbing, the longest course is the definite benchmark of the day.
