What you'll find on site:
Course focus:
On the agenda: racing down mountain slopes, spectacular panoramas, snow-capped peaks of the Mont Blanc, surrounded by thousands of trail runners and supporters.
The 90 km, 42 km and 10 km events start and finish in Chamonix. You do a loop, heading towards Switzerland which you'll reach on the 90 km trail. A great chance to wave hello to the neighbours! The marathon route follows the ultra via the Tête du Prapator, Le Petit Balcon Nord, l'Aiguilette des Posettes… before a clever U-turn before the border.
If you're running the 23 km, don't miss the turn at Montroc or you'll find yourself on a completely different course you didn't sign up for 🥲 Finish expected at Planpraz where you'll cross paths with the Kilomètre Vertical runners. Who will have just tackled 3.8 km of uphill against the clock, as breathtaking as it is STEEP. To each their own challenge!
Warning: some of the trails require a good fitness level. Do your research before diving in, prepare in advance and enjoooyyy!
