UT4M race trail training, 3 days

UT4M race trail training, 3 days | France

Join Caroline, UIMLA certified mountain guide, trail running during 3 days in the massifs of Vercors, Oisans, Belledonne and Chartreuse, to train for the UT4M!



4 Days

Jul, Aug

Very high


Are you planning on running the UT4M? This trail running program is ideal to train and get to know the terrain in preparation for the race! 

We will run almost 120km of the UT4M race. We will go to all the key places, reach the summits, practice the technical descents. Besides, I organized this trip with the logistics of a transfer to transport our luggage and help us if necessary.

This is the best way to get prepared for the real race, enjoying the incredible variety of landscapes and the ambiance of Vercors, Oisans, Belledonne and Chartreuse.

The highlights of this trip are: – A chance to properly get to know the UT4M – Advice from a professional – Logistics: transfers, luggage transfer, accommodation, meals

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 35km a day and go up from 1500 to 2500 meters. We will mainly be on single tracks and technical trails (stone, névé…). We will partially run off trails and be on aerial paths.

Ready to get familiarized with the route of UT4M during 3 intense and rewarding trail running days? Then book this trip and let’s get ready for the real deal! I also offer a similar program but in preparation for the UTMB, check it out here.

What people are saying about -Caroline


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.


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!


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.



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.



Well organized tour of the TDS course. Amazing views await even if you’re not planning to run the race
