Departure at 11:59 p.m.
IT 100
The legendary 100k distance
in the heart of the Vosges!
This three-digit distance is a benchmark in the world of trail running. That's why, from 2023 onwards, it will be one of the ultras that make up the Infernal. Difficult and among the most prestigious distances, you'll need to tame the Massif des Vosges to claim the title of finisher of this race.
Mind you, it's inspired by the biggest race of them all, the IT200, but it's not half as demanding. For those still looking for the ultimate challenge, it can be completed in teams of two (duo) over a distance of 50km each.
Opening on 01/01/2025
A prestigious 100 km course
This race marks the culmination of a mythical quest for ultrarunners. Accessible to the most highly trained runners, it is also open to experienced runners in search of the ultimate distance, or a gateway for the most seasoned.Â
En solo ou par équipe de 2 (à venir)
(Relay registration opens soon!)
As the challenges are often done in teams, it will be possible to share this race with the person of your choice by forming a team of two. Be careful, you'll need to choose the right person so that together you can become the finisher of this relay event! This choice is also the right way to run a 50km Infernal, a format that doesn't exist. So, are you convinced?Â
In 2024, the relay will take place at the Rochesson refreshment station (52km and 2400D+).
Night departure, Day arrival
Just like the big ones, the start will take place at the same time as the IT130, in a unique and magical atmosphere, as we know how to do here in the Vosges. By day or by night, you'll need to be clear-headed to reach the three-figure milestone everyone's dreaming of.
Col des Hayes and guides
Accompanying persons will not be allowed to enter the Col des Hayes refreshment area by car. Cars may be parked a few hundred metres further down.Â
Lightening bags
A lightening bag is authorized for the IT100 (see regulations).
