First run in 2003, many now consider the UTMB to be the world’s most famous trail race. Encircling Mont Blanc, the race starts and finishes in Chamonix, a town long-considered to be the home of alpinism. It passes through Courmayeur, Italy, Champex, Switzerland, and includes several high passes around the Mont Blanc massif. Today, the UTMB series includes a variety of other races which take place during the last week of August. Entry is by lottery, and each race requires a specific number of UTMB points, which are allocated based on the difficulty of designated qualifying races.
