Ascent and descent of Mont Blanc Map

In July 2013, I set the fastest known time for the full ascent and descent of the Mont Blanc.


This route, the historic Grands Mulets, covered a total of 28.4km and started on the French side of the mountain at the church square in Chamonix.

It ascends to the west of the Bosson Glacier and the well-known trail "La Jonction" trail, followed by the route to the Grands Mulets refuge, before arriving on the Petit and Grand Plateau and the steep climb to the Bosses Ridge, past the Valot refuge and eventually to the summit of Mont Blanc at 4810m.

I made the summit in an incredible time of 3 hours 33 minutes.

On the descent, followed the same route and reached the church square in Chamonix with a final time of 4 hours and 57 minutes, breaking the record of 5 hours 11 minutes that was set in 1990 by Pierre-André Gobet.
