Why shouldn’t you miss this?

A real playground!

Between discoveries and quirky passages, the UTWB course is full of surprises.

With 7 “Urban Trail” sectors, the atmosphere will be at times bucolic, festive, or completely unexpected—like when you’ll be running straight through the town hall lobby.

To fire things up, 4 Fan Zones and 2 aid stations are strategically placed so supporters can cheer you on multiple times within a short radius.

And finally, get ready to feel the thrill as you charge through the supporters’ corner at the top of the day’s biggest challenge: the cobblestones of the Hondenberg.

🏆 Rankings for everyone


Rankings by distance, gender, age group — and even a special climbing challenge

Everyone’s welcome, whatever your level!
