Urban Trail de Watermael-Boitsfort

About the race

The Urban Trail de Watermael-Boitsfort (UTWB) is a city trail through the streets and paths of Watermael-Boitsfort, organised by Beautiful Sports. Start and finish are at the Trois Tilleuls stadium. You choose between 11.7 km and 7.11 km; both routes have been renewed and signposted for 2026, and you can also download the GPX. Halfway there's a refreshment stop at the town hall. Runners set off in waves between 10 and 10:35 am, the children's races on the athletics track start earlier. There's chip timing, with changing rooms and showers at the sports centre. Walkers get a separate route.
