CCC Aid Station Planner

The CCC (Courmayeur-Champex-Chamonix) is a 101km UTMB World Series race that covers the final two-thirds of the UTMB course in reverse, starting in Courmayeur, Italy and finishing in Chamonix, France. With 6,100m of elevation gain, it shares the same high mountain terrain as UTMB but at a more accessible distance.

The opening climb from Courmayeur. Unlike UTMB which arrives at Courmayeur after 79km, CCC runners start there fresh and immediately climb to Refuge Bertone (900m D+ in 7km). This opening test sorts runners early - going out too hard on the Bertone climb is the most common early mistake.

Shared terrain with UTMB. Runners who have studied UTMB know the Grand Col Ferret (Swiss border crossing), La Fouly, Champex-Lac, Trient, and Vallorcine well. The key difference is that CCC runners cover this section fresher than UTMB runners - which can lead to pacing errors in the other direction (going too fast because the legs feel good after "only" 40km).

The final climb to La Flegere. At 82km, the 1,200m climb to La Flegere is the last major effort before the descent into Chamonix. For runners finishing in 18-22 hours, this climb arrives in the early morning hours. Pacing this section conservatively determines finish condition.

Crew access points: La Fouly (37km), Champex-Lac (46km), Vallorcine (70km). Drop bags allowed at Champex-Lac and Trient.
