La Boucle du Pic du Diable is a small nature race in Saint-Pierre, on the island's south side. Its main event is typically a short trail of about 21 to 22 km, held in March and starting in the morning. OXYTRAIL organizes the race, which falls into the Trail XS / short-trail category, making it more of a local off-road run than a long mountain ultra.
The main trail appears manageable: sources indicate either 21 km with 200 m of elevation gain or 22 km with 100 m of gain. The route includes some elevation but not a significant vertical profile. The event also features a 5 km hike and a children's race, broadening the day's activities beyond the main trail. Listings suggest a straightforward Saint-Pierre nature event centered on Pic du Diable, with runners, walkers, and families participating.
