Trail des Forts

Trail des Forts of Besançon: running through history and nature

The Trail des Forts of Besançon was born in 2004 from the initiative of Olivier Tiercet and Jean-Marie Baverel, two members of the running section of ASTB (Amicale Sportive Territoriale Bisontine). Their goal: to showcase their excellent training ground, their city, and the surrounding hills dotted with Vauban fortifications classified as UNESCO World Heritage sites.

Courses for all levels

The Trail des Forts offers a complete range of courses adapted to all runner profiles:

• 5 km night race — Time trial with 140 m of positive elevation gain
• 11 km — Discovery trail with 330 m of elevation gain
• 16 km — Intermediate course with 560 m of elevation gain
• 22 km — Nature trail with 600 m of elevation gain
• 42 km — Major event with 1,300 m of elevation gain
• 62 km — The premier event with 2,400 m of elevation gain, solo or relay, connecting the city's 10 forts

A legendary passage through the Citadel

All runners have access to the famous Citadel of Besançon and its breathtaking passage offering an unimpeded view of the finish line. The main course even connects the 10 forts from the 18th and 19th centuries that protect the Vauban city.

Impressive growth

The first edition in 2004 had 400 runners on a single 32 km course, in terrible weather conditions: torrential rain, biting cold, and very muddy terrain. Since then, the event has continued to grow to become one of the largest trail races in Eastern France, with over 7,650 registered participants — a maximum capacity that the organizers no longer wish to exceed.

A sporting and heritage event

Beyond the sporting dimension, the Trail des Forts is a true heritage tour. Runners cross remarkable natural landscapes, forests, ridges, and historic military structures. The partner village set up at La Rodia offers changing rooms, a podium, and entertainment for companions.
