Trail running Haute Route des Geants

3 days in the beautiful Valley of Aosta, partially on the trail of the famous Tor des Geants race, with Caroline, UIMLA certified mountain leader.



3 Days

Apr, May, Jun, Jul, Aug, Sep, Oct, Nov




This 3-day trail on the Haute Route des Geants takes over the first part of the mythical Tor des Geants path (330 km and 24000 meters of altitude change). Indeed, it's the longest endurance test mountain trail.

From the Courmayeur station at the foot of Mont Blanc until Cogne at the Gran Paradiso National Park you will thrive in magnificent landscapes of the high mountains through passes and valleys in the company of Jules-Henri, 2011 winner of Tor des Geants.

Enjoy exploring this region and the exceptional nature which composes it!

The advantages of this trail course are the following:
– The presence of Jules-Henri, team SALOMON athlete
– Part of the legendary route of Tor des Géants with one of its winners
– The discovery of the Val d’Aoste with the Grand Paradis National Park
– Professional advice to improve while having fun
– Perfectly organized logistics: transfer, luggage transport, accommodation and meals
– Running with a light bag

Our housing will be in cottages and hotels (accommodation in dormitories and shared rooms).

In the ‘extra’ section below, you’ll find information about the required trail running level you need to have. You will also see the equipment that you need to bring with you.

During these 3 days we will run on average 15-20km a day and go up from 1000 to 1500 meters. We will alternate between single tracks and large paths.

Do you find this 3-day trail course in Italy interesting? Then please contact me! We will discuss your level and the detailed program. Please note that I can not mix people for this course. But if you want to try it, you can come as a private group, with a minimum of 5 people!

If this tour does not suit you, I will present you other trail programs which I organize this year, in the Alps and elsewhere, for beginners and experienced trail runners, like this Trail running trip in Gran Paradiso. It will be a pleasure for me to take you through these beautiful mountain paths and coach you in your approach to trail.

Day 1: Courmayeur - La Thuile

17km, D+ 1364m, D- 1113m, around 4-5 hiking hours
9:30AM: meet in front of the Chamonix train station, then minibus transfer to Courmayeur (30 min). We start with the shortest stage but with amazing views of Mont Blanc and the Grandes Jorasses which we will find during the first ascent in the wild Arp pass (2571 m). A nice descent to the small valley of Youlaz before following a small path that leads us to La Thuile station. Dinner and overnight at cottage or hotel.

Day 2: La Thuile - Planaval

26km, D+ 2200m, D- 2280m, around 7-8 hiking hours
The second day will start with the beautiful ascent to the Deffayes refuge, where we will admire beautiful waterfalls! The refuge stands before the Rutor, and glaciers are near, a sign that we are reaching the high mountain. The next effort takes us to the Passo Alto (2857 m) in a rocky landscape. A beautiful descent follows. The field is technical but it is a splendid scene. The ascent to the Crosatie pass (2838 m) is made of many pins and the arrival at the pass is carved in stone. Finally, a beautiful descent takes us to the small village Planaval. Dinner and overnight in a hotel.

Day 3: Planaval - Eaux Rousses

26km, D+ 2675m, D- 2493m, around 9-10 hiking hours
We start the day with a gentle ascent to the village of Valgrisenche through alpine meadows, stone paths and larch forests. From the refuge, we follow the path of the Alta Via, and the Fenêtre pass (2840 m) marks the passage from one valley to the next. Then we will reach the Entrelor pass (3007 m), which marks our arrival to the Gran Paradiso National Park! The ibex and vultures observe us and after a nice descent we reach Eaux-Rousses, the end of our day! Dinner and overnight in dormitory.

Day 4: Eaux Rousses - Cogne

23km, D+ 1642m, D- 1765m, around 6-7 hiking hours
For the grand finale, we will borrow the “Géant du Tor”, the Loson pass (3296 m). This stage at the heart of the Gran Paradiso National Park follows the hunting trails of King Victor-Emmanuel II. After the forest, we reach the rocky world up there! The pass is set between two mountains and the blue rock renders the place magnificent… Sublime! It is now time to descend towards the crested Cogne station. Finally, return to Chamonix by bus in the end of the afternoon.

Great experience, but definitely favored toward elite runners. One of our guides, JC, was amazing. He cared about every runner. The other guide seemed only to care for the elites (and himself). On top of Col des Montets, I asked if we had time to put on warm layers. The guide said "of course," but then quickly proceeded to run off with the entire group while I stood bare and freezing with my gear unpacked. Total lack of consideration for the well-being of his runners. Otherwise a great tour.

Mon stage initiation trail à La Plagne avec Caroline a été une très belle expérience. Son expérience sa disponibilité son sourire m'ont permis d'assimiler les bases du trail. Mes compères et moi même avons progressé jour après jour toujours dans la bonne humeur. Aujourd'hui je me sens capable de faire mes premières courses avec des bases techniques, alimentaire et de sécurité. Je compte continuer mon apprentissage avec un stage intermédiaire en 2017.

Pour moi le trail c'est avant tout la découverte de nouveaux territoires, les rencontres et les échanges avec d'autres passionnés, le respect de la nature. Mes 3 stages avec Caroline m'ont permis de retrouver ces fondamentaux dans un cadre toujours bon enfant, mais pas moins professionnel. Caroline est une passionnée de montagne et de tout ce qui y touche (sport, culture, gastronomie) et elle sait comme personne transmettre sa passion et ses bons conseils, toujours avec le sourire. Je garde un excellent souvenir des rencontres avec les autres stagiaires et mais aussi avec les autres encadrants, Guillaume, Seb, Cédric, Lydie et tant d'autres rencontrés au cours de ces stages.

J'ai fait deux stages avec Caro, c'est devenu une amie, et chacun de ces stages m'a laissé des souvenirs inoubliables. Le premier stage en 2014 en Haute Savoie à l'occasion du Trail du Gypaète. Le Deuxième stage en 2015, dans les Calanques de Marseille. Ces stages auront été parfaits à tous les niveaux: Paysages grandioses (on sent qu'ils ont été choisis avec soin), des échanges techniques avec des "pros" (un grand moment quand Caro inspecte les sacs à dos...), pleins de conseils nutrition - mode de vie etc... La découverte des autres stagiaires mais aussi des autres encadrants (très bon contact avec Guillaume Lenormand par ex.). Des conditions matérielles top (hébergement, repas, organisation etc...). Seule critique: le temps passe trop vite, c'est toujours trop court! Donc au final quand c'est fini, on n'a qu'une envie... c'est de repartir pour un autre stage! Et vu le nombre de personnes que l'on croise sur les stages qui en sont à leur n-ième participation, je peux affirmer que ce sentiment est partagé!

J'ai eu l'opportunité de participer à deux stages, l'un dans le Cantal, l'autre à Chamonix. Un grand plaisir de partager une passion commune avec des participants très sympas de tous niveaux et de tous horizons. Caroline, une grande professionnelle de la montagne et du trail, n'a pas son pareil pour organiser ces rencontres, et tout cela dans une super ambiance et des paysages à couper le souffle.
