UTDS 27KM

The dynamic format that sets the tone

Starting in Stoumont, this 27-kilometre stage of the Ultra Trail des Sources embodies the essence of Ardennes trail running in a rhythmic and, at first glance, accessible route: 785 metres of elevation gain, more than enough to remind you that it’s never flat here.

From the very first kilometres, the course demands a fast pace with a succession of short but steep climbs, playful descents and bursts of speed that call for full commitment from start to finish.

You run through a landscape typical of the region, amidst vast forests, river-carved valleys and more open stretches offering stunning views of the surrounding terrain. The variety of forest trails, smoother roads and more technical sections gives the race its rhythm and keeps it from becoming monotonous.

The terrain beneath your feet remains varied: sometimes soft, sometimes damp, sometimes a bit more crumbly, depending on the section and the weather.

At this distance, it’s all about pacing: short enough to run fast, demanding enough to punish over-enthusiasm.

If you start too fast, those bursts of speed will ultimately cost you dearly; if you pace yourself well, you can enjoy the course to the full and show off your speed.

A dynamic, intense format, perfect for discovering the UTDS or testing yourself on a fast but uncompromising trail.
