Mont-Blanc Marathon is one of the world's premiere trail races, and starts in Chamonix's central square before leading runners on a 26.2-mile loop around the surrounding valley. Along the way, racers pass through ancient hamlets and high-alpine meadows, all in the shadow of Western Europe's highest mountain. This is ultra athlete Kilian Jornet's training ground, so be prepared for a burly ride, including more than 8,000 feet of climbing.
