Tour du Mont Blanc- 1st Half route

  • The route follows the Ultra Trail Du Mont Blanc, one of the world's toughest races.
  • You will start in Chamonix and head down the valley to Les Houches before making your way up over to Les Contamines via one the high passes at around 2100m.
  • You'll run past glaciers and through alpine meadows and get a feel for how stunning this area is.
  • The first night is spent in Les Contamines before carrying on to the steep climb over the Croix du Bonhomme. The views from the Croix back down the valley and towards Geneva are incredible.
  • From there we head down to spend our second night at Les Chapieux, a remote hamlet and a great place to unplug from the world for one night.
  • The next morning as the sun rises from behind the Aiguilles des Glaciers you will climb up to the Col de La Seigne, which marks the border with Italy. From here the route stretches into the horizon along the valley leading to the mountain pass 25 miles away which marks the border with Switzerland.
  • The route sweeps down into Italy, staggering views of couloirs and rock buttresses towering on the left, leading up to Monte Bianco. The path undulates on nice smooth trails before a last climb, and then a steep descent into Courmayeur.
  • Here you will spend your last night and celebrate your incredible achievement of running 50 miles of the epic Tour du Mont Blanc.

Poles: Although not mandatory, trail running poles are highly recommended for this trip, especially if you are taking part in the TMB or similarly longer trips. They have been proven to help! We recommend Leki's lightweight trail running poles due to their comfort, durability and design. We demonstrate how to use poles correctly on all of our trips, including in the UK.


Although spectators are welcome to come and watch this race, the length and duration does not make for a particularly good spectacle and spectators are responsible for their own travel and accommodation.

Frequently Asked Questions

What is trail running?
Trail running is simply one of the best ways of discovering and exploring the best nature has to offer. It is a fantastic form of exercise and the health benefits are countless. However there are also hazards and variables to be considered when trail running. To find out more about these considerations, visit the British Mountaineering Council's website. Our Lead Runners are equipped with emergency survival kit as well as a basic first aid kit. Mobile phones are used to communicate in the mountains.
How long is this event?
This portion (the first half) of the trip takes place over 3 days, and averages ~17 miles (27KM) per day. Much of this route involves hiking (rather than running) because of the steep inclines.
How difficult is this event?
Very difficult, it is recommended that all participants have a strong level of fitness. The Alps are notoriously steep and will test participants' strength.
Can I bring my dog?
RunTheWild loves dogs and many of their events are dog-friendly, but please reach out to them directly to confirm there is space for your furry friend.

Since 2013, Run the Wild has been dedicated to delivering incredible trail running adventures in the UK and European Alps. Trail running is the ultimate pursuit of freedom, of feeling alive and it's something we are really passionate about! There’s nothing that compares to the feeling of running along mountain paths and for a moment leaving behind your busy life. Start YOUR amazing journey with Run the Wild! The company was founded to bring this experience of running trails in the wild; free of the usual race and logistical burdens, to you. We love exploring places, not just running races. We love meeting people and having an adventure together. We like races too, but this is where our heart really lies and if we can help you have more fun running trails; whether to see the sun rise over Mt Blanc as you climb up over a mountain pass, or indeed to check out a future race route then we will be happy! Join us running off into the unknown, the path flowing underneath your feet, snow capped mountains glinting in the sun, clouds melting away in the valleys far below. Setting your heart and mind free... Exploring places... not running races. This is what it feels like to be alive! “The mountains are calling and I must go.” John Muir, Meet the team.
