TRAIL DU PAYS DE SULLY 2026

About the Event

Immerse yourself in the natural beauty of the Vexin Regional Park for an unforgettable trail running experience. Nestled within the picturesque landscapes surrounding Sully, a historic site steeped in history from the era of Henri IV, this race offers runners a unique blend of challenging terrain and serene surroundings.
Competitors will navigate through the lush forest of Rosny-sur-Seine, where winding paths and rolling hills provide both scenic vistas and technical challenges. The event features four distinct courses catering to various skill levels:
A 11-kilometer trail that ascends over 300 meters in elevation offers a compact yet intense course for those seeking a shorter but still demanding route.
For longer distances, the 15-kilometer march takes runners through varied terrain with an ascent of 400 meters. This option is perfect for endurance enthusiasts who enjoy scenic views and moderate climbs.
The 19-kilometer trail presents a more rigorous challenge, with a total elevation gain of 530 meters over its length. It combines technical sections with sweeping panoramas along the Seine River’s winding banks.
Finally, the longest course at 31 kilometers challenges even the most experienced runners with an ascent of 800 meters and extends through some of the park's most rugged terrain.
All courses are clearly marked and feature well-placed aid stations offering both solid food options and hydration. Participants must bring their own reusable cups for sustainability, while a water bottle is highly recommended to stay hydrated throughout the event.
Join us in this celebration of nature’s beauty as you test your limits against some of France's most stunning natural landscapes.
