11:45 AM Update

It appears as though some major competitors will choose not to start the race after learning of the announced course changes.

Per Miguel Heras, “He decidido tomar la salida, aunque el trazado no me favorece. Mis compañeros de equipo no correrán, ha sido decisión personal de cada uno.”

English translation by Roger Soto, “I’ve decided to start even if the route doesn’t suit (favour) me. My teammates aren’t running, each one of us has taken his personal decision.”

11:30 AM Update

Weather conditions too difficult on Col du Bonhomme, Col de la Seigne, and the Grand Col Ferret.

The UTMB departs around 19:00 on an alternate course in France.

The first part of the UTMB route remains unchanged, then returns to La Balme, Les Contamines, and Les Houches and by a different route. It will then run along the valley of Chamonix to just before the Col des Montets to join the CCC route to return to Chamonix by way of Argentiere.

100km, 6,000 meters of climb.
Maps of new routes and time barriers available soon.
