Trail, hiking, ultra-trail, vertical kilometer… So many formats to find at the Marathon du Mont Blanc. In addition to the marathon format, of course. Grab your bib and get ready for the experience of a lifetime!

 

What you'll find on site:

  • A Trail Camp with some of the biggest 100% outdoor brands;
  • Stretches of forest, verdant plains and vertiginous mountains;
  • 8 races ranging from 350 m of elevation gain to 6330 m of elevation gain;
  • Aid stations (note, you are in semi-autonomy!), first aid posts, toilets, in short, the essentials for a comfortable trail (you know what we mean).

 

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!

 

3 reasons to participate:

  • The physical and mental challenge: from preparation to race day, you push your limits;
  • A start and finish worthy of a star. Fired-up crowd (yes, that counts.);
  • Sightseeing: Haute-Savoie region, Switzerland, Italy… perfect walks for active recovery.
