The Trail des Violettes begins at Stade Maxime Marchand in Louviers, France, held in late March over predominantly natural and forest paths. Organized by l'Etoile Athletique Loverienne, this trail-running and walking event offers three distances: 12 km with 230 m elevation gain, 25 km with 600 m, and 42 km with 1000 m. The 12 km route is also available for walkers, including Nordic walkers.
The event has runner caps: 420 for the 12 km and 25 km races, and 240 for the 42 km. Separate limits apply to timed and non-timed 12 km walks. The 42 km is run in semi-autonomy, requiring participants to carry some supplies. Now in its 10th edition, the race does not offer same-day registration, contributing to its organized, local-club atmosphere.
