The course takes participants through the Calestienne region, a limestone strip that provides a unique ecosystem and rugged topography. While typical trails focus on surface elevation, the Trail des Grottes challenges athletes with the humidity and unique footing of the underground galleries. The race is part of a broader seasonal calendar that includes the "Backyard Beauraing" and "La Tournée des Corridas," cementing its place as a staple for endurance athletes in the Wallonia region.
Participants can register online via the official portal provided by the organizers. Because the route passes through a protected nature domain and sensitive geological formations, registration is subject to strict participant caps to ensure both safety and conservation. Runners are encouraged to prepare for a mix of dark, subterranean paths and the lush, green trails of the surrounding Lesse valley. For further inquiries or group registrations, the event management team can be reached via their official email at [email protected].
