The Ainfernale

L'Ainfernale is an inclusive, festival‑style obstacle course held in Marboz in the Ain department of France. The event brands itself as a fun and convivial parcours d'obstacles with new obstacles announced for 2026 and an emphasis on participation rather than competition. The official day schedule lists a course start in the early afternoon and later community events on the same evening, so the occasion is as much a local celebration as a sporting challenge.

On the day there are community features around the start village including food and music; the programme published on the event site highlights a meal‑concert with the group AndJoy at 19:00 and an outdoor dance (bal) at 22:00. Registration is via the organiser's official site and linked sign‑up page, and the event information repeatedly stresses a friendly, non‑obligatory approach to obstacles so participants can run or walk at their own pace. For full technical rules, the organiser's règlement and the programme pages should be consulted prior to attending.
