Trail des Tours - 40 km 2026

The Trail des Tours - 40 km is a 40-kilometer trail race starting in Montfort-l'Amaury, located in the Yvelines department west of Paris. This event is part of the Trail des Tours series, which also offers 15 km and 28 km distances, making the 40 km the longest option available. Classified as a Trail XS event, it features 400 meters of elevation gain and a 7:00 start time, suggesting a course that is primarily runnable rather than a mountain ultra. The race was previously known as Trail des Cerfs. Its location in Montfort-l'Amaury provides a small-town start in the Ile-de-France region, differing from a large metropolitan race setting. Detailed course information, including a profile and GPX track, is available for runners who wish to review the terrain beforehand. Kikourou includes the race in its endurance sports calendar, allowing participants to share reports, training notes, personal results, videos, and engage in forum discussions.
