The 100 km of Steenwerck

Steenwerck 100 km

In Flanders, the Steenwerck 100 km takes place on a completely flat, paved course between the village and the surrounding countryside. After an initial loop through the town, runners complete three laps that pass through the neighboring municipalities of Le Doulieu and the hamlets around Steenwerck.
Passing through the village repeatedly means runners regularly encounter spectators and aid stations. The event also retains a 24-hour Open format, alongside the classic race limited to 14 hours. In 2026, Steenwerck hosted the French 100 km Championships.
