Training camp for the “90km du Mont Blanc” in Chamonix (4 days)

Training camp for the “90km du Mont Blanc” in Chamonix (4 days)

Caroline, a UIMLA-certified guide, will lead you on this thrilling and challenging 4-day training camp to ensure you are in the best condition, both physically and mentally, to tackle the 90km du Mont Blanc in Chamonix, a spectacular setting to train in.



4 Days

May, Jun




  • Trail run in the shadow of Mont Blanc in the world-famous Chamonix!
  • See some of the most spectacular and pretty views in Europe!
  • Push yourself to new physical limits on this challenging training camp!


I invite you to join me on this 4-day trail running training camp, where we will push each other to new highs and achieve our goals by running around the beautiful paths and trails in the shadow of the majestic Mont Blanc, where we will train and prepare for the same path as the 90km du Mont Blanc race in the world-famous and internationally-renowned region of Chamonix.

The stunning, tranquil and idyllic area of Chamonix in France has been attracting visitors and outdoor enthusiasts for decades, such is the stature with which its scenery and conditions are held in. Trail running in Summer is a particularly popular pursuit, as the paths and trails available are second to none owing to the superb terrain and abundance of stimulating views.

We meet on the first day at our hotel in Chamonix, and from there we head off to trail run in earnest, as we go about completing the course that runs between Chamonix and Planpraz.

The subsequent three days follow a very similar pattern, as we go from Planpraz to Vallorcine, Vallorcine to The Wood and then finally The Wood back to Chamonix.

This is excellent preparation for the 90km du Mont Blanc, as we will be following the exact path of the race, giving you the best training possible.

Along the way you will be exposed to some of the most pretty and alluring views and scenery in Europe, as the forests, snow-capped mountains (including the towering Mont Blanc) and pristine lakes, combined with the clean, crisp, fresh air makes for a pleasing and intoxicating experience.

We finish the training on day 4 and head back to the hotel where we started, hopefully feeling fitter, happier and more determined to run at greater heights and distances!

Improve your fitness and take in the glory of Chamonix all in 4 days – book now to experience!

I also offer trail running from Chamonix to Zermatt, here!

Alternatively, I offer guided trail running in the Alps, here!

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.
