The North Face® Ultra-Trail du Mont-Blanc®
www.ultratrailmb.com
The challenge is massive: it is a complete tour around the Mont Blanc starting and ending in Chamonix (France). The route passes through France, Italy and Switzerland. This extreme challenge involves many difficulties, the main ones being the distance (166 km), the altitude (19,000 meters altitude change - 9,500 m of ascent and 9,500 m of descent), and the duration (the route must be done within 46 hours).
This race is 60 percent longer than the Ultra Marathon completed by Olivier in 2008. Some 2,300 competitors start, though generally some 40 – 50 percent do not finish.Profile
