Trail Godefroy Bouillon Winter, live.

A winter trail in the Semois valley from Bouillon castle

The Trail Godefroy Bouillon Winter is a one day winter trail race in the Semois valley, starting from the Esplanade du Château in Bouillon in the Belgian Ardennes.

The 2nd edition is on Saturday 13 February 2027. The event was first run in 2026 as the Castle Trail Bouillon and now carries the name of Godefroy, in whose footsteps the courses run. It is organised by Trailrun.be and the base camp is on the castle esplanade.

There are three distances, all starting from the Esplanade du Château. The Godefroy 50 covers 50 km with 1,923 m of climbing and starts at 8:00. The Godefroy 20 covers 20 km with 736 m and starts at 9:00. The Godefroy 35 covers 35 km with 1,336 m and starts at 10:00, in two waves. Bibs can be collected the evening before, from 18:00 to 19:30, or on race morning from 7:00.

Expect wild trails through the Semois valley in winter conditions, with steady climbing on every course. The 20 km is a fair entry point for runners new to winter trail, the 35 km a solid half day, and the 50 km a long day for experienced trail runners. All three distances count towards the UTMB Index.

Supporters can wait for the finishers at the base camp on the castle esplanade, where beers from the Rochehaut brewery in the Semois valley are served, including the alcohol free La Bluffante.

On Livebib you can follow a participant who chooses to share their own live position from the phone they carry. This is not the organiser's timing, and the official results come from the organiser.
