UTDS 160KM

UTDS 160KM

You don’t come to finish it. You come to keep going.

During the 160 km Ultra Trail des Sources, you’ll traverse the Ardennes, between Spa, Stoumont, Trois-Ponts and Malmedy, where dense forests, steep valleys and more open terrain near the High Fens follow one another without giving you a moment’s respite.

Here, the terrain dictates the pace: irregular climbs that disrupt your rhythm, technical descents that exhaust your quadriceps, constant bursts of speed that slowly wear you down, and all this on often damp ground where grip remains uncertain. Water is omnipresent; streams and springs accompany your progress, but make the course lively, demanding and sometimes treacherous.

As the hours pass and night falls, everything changes: clarity becomes an asset, every stretch seems longer and the effort becomes as much mental as it is physical. You cannot simply endure these 160 km; you must build them up carefully, paying attention to pace, nutrition and energy.

For here there is no major respite or easy stretch, only a succession of challenges that ultimately make the difference.

As you approach the finish, there isn’t much left on the course, but it’s all in your legs: and there, in that final burst of strength to push through one last time despite the fatigue, you truly understand what the UTDS is all about.
