Trail de la Vallerustie is a small Corsican trail event based in San-Lorenzo, in Haute-Corse, with the start set above the San-Lurenzu town hall. The race is simple on paper but steep in practice: one 15 km trail course with 1,200 metres of climbing, starting in the morning. A 6 km walk starts shortly after the runners, giving non-racers a shorter way to join the day.
The event keeps a village-race feel, with bib pickup in the morning, a shared meal from midday in the San-Lorenzu festival hall, and prizes handed out only after the last trail runner has finished. The walk raises money for Espoir Autisme Corse, and everyone needs to bring an ecocup because cups are not provided on the course.
