The Sure-to-Sure Swimrun race will be held in Esch-sur-Sûre, in the North-West of Luxembourg at 175km’s from Brussels. This region is arguably one of the best locations for swimruns imaginable. The way the river Sûre meanders through the hills makes for ideal and safe swimming distances while the dense forests around Obersauer Nature Park and the surrounding hills hold truly magnificent views. We fell in love with this beautiful place and decided to organize our own version of the popular endurance sport: The Sure-to-Sure Swimrun Luxembourg!
