The Ronde des Vergers begins at the Moulin à huile, Maison Leydier, in Saint-Martin-de-Crau, a town in Provence situated near the Camargue and the Alpilles. Held in October, it features 5 km and 10 km races, along with walks covering the same distances. This variety accommodates runners, walkers, families, and individuals seeking a brief nature excursion instead of a lengthy road competition.
The course winds through olive groves, peach orchards, and sections of the Crau Nature Reserve, a unique protected steppe environment in Europe. While significant elevation changes are not noted, the natural ground requires some preparation. The event, now in its third year, has become a way for participants to explore the Crau steppe on foot.
