Lore & Trivia
CCC (Courmayeur-Champex-Chamonix) is UTMB's little sibling — 101km with 6,100m of gain through the Italian and Swiss sections of the Mont Blanc massif. For many runners, CCC is the perfect ultra: long enough to be a genuine mountain test, short enough that you can actually race it rather than just survive. The course starts in Courmayeur, Italy, crosses the Grand Col Ferret (2,537m) into Switzerland, passes through Champex-Lac, and descends into Chamonix. The finish in Chamonix's town centre — running down the Rue du Moulin as thousands of spectators cheer — is one of the most electric moments in trail running. CCC attracts a mix of ambitious first-time UTMB participants and elite runners using it as a stepping stone to the full loop.
