Foulées nature bruzoises is a nature-running event on the Ker Lann campus in Bruz, Brittany, held in early October. Participants select from two short off-road routes, approximately 5.3 km and 10.1 km, with a total limit of 500 runners. The shorter race is for younger teens and adults, and the longer one is for older teens and adults.
The course is set around the Kerlann campus, giving the race a local and contained feel. The event is approaching its 47th edition. In a recent year, participation records were broken with over 500 runners in the program, including many children. Licensed runners can register with French athletics or triathlon federation credentials; others require the PPS health form. Bib pickup and last-minute in-person registration occur at the Intermarché in Bruz on Saturday afternoon. Bib pickup is also available at Ker Lann on Sunday morning before the races begin.
