100 km | 6100 m elevation gain |
Courmayer, Champex & Chamonix, Europe

  • Italy➡️ Switzerland ➡️France

    1. Stunning scenery 🤩

    2. Cowbells rung through villages and in aid stations.

    3. Finishing the run through Chamonix feeling like a hero!

  • Queues - especially on first climb.

    Overtaking on single track. Very long climbs and descents compared to UK.

  • It's a good step towards UTMB, as it's effectively the final 100km of UTMB's 170kms.

  • You'll need UTMB running stones to enter the ballot.

  • The atmosphere in Chamonix during UTMB finals week is amazing!

    But if that doesn't float your boat, then consider doing this as a self guided tour as the TMB route is well marked and there are mountain huts you could stay at along the way!
