Troll'Hoween - Pierre-Châtel 2026

Troll'Hoween is a Halloween running and trail event in Pierre-Châtel, Isère, organized by Troll Team Triathlon. The program begins with children's races at 17:00, followed by the adult races at 18:00: a 10 km trail discovery option for solo runners or adult relays, and a 17km trail with 350m of elevation gain. The event is based on a straightforward local concept: to provide Pierre-Châtel with a festive Halloween outing suitable for children, solo runners, and relay teams. Its history is brief; Troll Team Triathlon initiated Troll'Hoween in 2025. Therefore, its clearest identity currently lies in its Halloween timing, evening schedule, and the selection of accessible formats.
