Trail'loween 2026

Val'Oween Trail is a Halloween-themed trail event in Isère, centered on running after dark instead of a typical daytime race. It provides multiple routes and difficulty levels, including semi-night and night trail runs, hiking options, and children's races. This allows adults, families, experienced runners, and beginners to select a suitable distance. The event embraces Halloween rather than using it as a mere theme: costumes, candy, and some planned scares are included. The combination of night trails, walks, and kids' races creates an atmosphere more akin to a local Halloween gathering than a competition solely for dedicated trail runners.
