[A CONFIRMER] Trail des Sept Hameaux - 12 km 2026

Trail des Sept Hameaux is a trail-running series held in Magny-les-Hameaux, within the Yvelines region of Île-de-France. The current schedule features a 12 km race and a longer trail option, approximately 23 to 24 km with about 330 metres of elevation gain. This is an off-road event, so participants should anticipate trails, varied paces, and some ascents, differing from a flat urban course. The series has adjusted its distances over the years. Previous options have varied from short trails of 12 to 14 km to longer routes in the high 20s and low 30s. A timed Nordic walking event has also been part of the schedule, contributing to a wider outdoor sport focus beyond just running. The recurring name "Sept Hameaux" refers to the local hamlets surrounding Magny-les-Hameaux, grounding the event in its local setting rather than a major city course.
