Tour du Mont Blanc

Ultra Trail Tour du Mont-Blanc takes place once a year in the Alps, across France, Italy and Switzerland. The distance varies between 150 and 160km, with a total elevation gain of around 8500m. The race is run in one leg.

While the best trailers complete the loop in slightly more than 20 hours, most runners take 30 to 45 hours to reach the finish line with the cut-off set at 46 hours.
