Chaque été de nombreux événements, aussi bien culturels que sportifs ont lieu à Chamonix.
An amazing spectacle drawing thousands of spectators: a Technical event in which pairs of climbers compete against each other by lead climbing a route on sight, and the Speed event, an impressive show of agility in which two top-roped climbers go head to head in a race to the top. With about 15000 spectators last year, it is an incredible sight to see.
Mont Blanc Marathon
Including the infamous Mont-Blanc Vertical KM, the Mont Blanc Cross (23 km), the Mont Blanc 10KM and the Mont-Blanc Marathon (42 km).
