UTDS 42KM

UTDS 42KM

The legendary race, Ardennes edition

Starting in Lorcé, this 42 km section of the Ultra Trail des Sources embodies all the symbolism of the ‘king’s distance’ and sets it against the demanding backdrop of the Ardennes: 1,437 metres of elevation gain, varied terrain and enough undulation to make this trail marathon a real challenge. Here, you’ll quickly forget the reference points of a road marathon.

From the very first kilometres, the course dictates its own pace with a mix of steep climbs, occasionally technical descents and bursts of speed that demand both leg strength and control.

You’ll traverse deep forests, enclosed paths, valleys carved by water and more open stretches where the landscape stretches across the surrounding hills. At times the view stretches far; at others, you’re swallowed up by the woods and the terrain.

This variety of landscapes adds excitement to the race, but at the same time reminds you that nothing comes for free here. Under your feet, the terrain is constantly changing: soft ground, muddy sections, fast trails, rougher sections.

Over 42 km, the classic mistake is to start at a classic marathon pace; but in trail running, and certainly here, it is pacing yourself that determines the outcome of the race.

If you remain patient in the first half, the course can become a stage on which to showcase your abilities.

If you waste your energy too early, every climb becomes a wake-up call.

A legendary route, yes… but done UTDS-style: tougher, more technical, more authentic.
