CourmayeurChampexChamonix

The Courmayeur-Champex-Chamonix (CCC) is a mountain ultramarathon that forms part of the Ultra-Trail du Mont-Blanc (UTMB) event series. The course begins in Courmayeur, Italy, passes through Champex-Lac in Switzerland, and finishes in Chamonix, France. The distance is around 100 kilometres, with roughly 6,000 metres of cumulative ascent, though exact figures may vary by year.

Runners on the CCC contend with high alpine terrain, long ascents and descents, and changing weather conditions in the Mont Blanc massif. The route crosses multiple national borders and offers alpine scenery that includes glaciers, valleys, and rugged peaks as it moves through mountain villages along the way.

Participation in the CCC is governed by UTMB’s entry system, which typically requires qualification points from other races and adherence to time limits at various checkpoints. The race is open to strong amateur and professional runners and is known for its challenging yet accessible format within the UTMB program. The event takes place annually in late summer, attracting a global field and contributing to the reputation of the Mont Blanc region as a premier destination for trail running.

In context, the CCC complements other UTMB races by providing a shorter but demanding Alpine route that links three countries and showcases the range of terrain and scenery found around Mont Blanc. It remains a prominent objective for international trail runners seeking a major alpine ultramarathon experience.
