Chamonix comes alive with trail running fever every August, when the UTMB comes to town. This unique set of 5 ultra trail races draws runners from across the globe and is the biggest event of the summer in Chamonix.
Around 8,000 runners take part every year, bringing with them family, friends and support teams. Thousands of spectators line the streets, clapping and cheering the runners on as they arrive back into Chamonix to cross the finish line.
If you're coming to the UTMB to take part, or just to watch the event, now's the time to start thinking about planning your trip and booking your accommodation.
