How to prepare for Tor des Géants — Complete Guide

The first trap with Tor is assuming a completed 100 miler is enough preparation by itself. The overall volume changes the nature of the race. Pacing has to work across multiple sunrises and sunsets, with long periods where the goal is no longer speed but continuing to make good decisions. Extended climbs, altitude, wet nights, tired eyes and the gradual breakdown of your stride create a type of wear that very few races reproduce.

Training therefore needs massive endurance, but above all high tolerance to repetition. The useful blocks are the ones that teach you to restart while tired, hike for hours in the mountains, manage your pack over very long stretches and remain functional as small problems accumulate: blisters, digestion issues, cold, sleep loss and mental friction. Tor rewards the absence of a major weakness more than pure speed.

Training should also include your in-race recovery model. Decide how you will use the life bases, which clothing or shoes you want to rotate, how you will protect your feet and when you will allow yourself meaningful stops. Even though each edition has its own details, Tor punishes passivity. Without a plan for sleep, bags and nutrition, you end up reacting to events instead of steering them.

That makes logistics central. Accommodation in Courmayeur before the start, movement in the valley, certificates and admin, bag preparation and any support planning all need to be clarified early. Because the race lasts several days, even small kit flaws become major issues. A mediocre headlamp, insufficiently tested shoes or a weak fueling routine can quickly turn into abandonment factors.

Starting from the TrailCompanion race page helps frame the format, and the Prep then turns that format into a sequence of concrete actions: training, gear, logistics checkpoints, nutrition, sleep and recovery. For a race like Tor des Géants, that structure is not a luxury. It is a practical way to reduce chaos.

Preparing well for Tor means accepting that no single strength is enough. You need a solid engine, but also durable feet, a calm head, meticulous organisation and a genuine respect for long time horizons. The more explicit you make those pieces before September, the better your chances of staying in your race when everything slows down.
