Trail du Grand Sénonais 2026

The "Trail du Grand Sénonais" takes place in Sens, Bourgogne-Franche-Comté, from 29 to 31 May 2026 and gathers a wide range of trail formats for all levels. The programme includes long-distance ultra trails, shorter trail loops, randonnée (walking) options and a children’s race, with distances reported from about 2 km up to the longest endurance routes. The event blends rural trails and local heritage around Sens and neighbouring communes, and the official pages highlight nocturnal and semi-nocturnal race variants as part of the weekend schedule.

Logistics on the official site note shuttle (navette) services from Salle/Complexe Roger Breton to start zones, clear barrier/cut-off times at aid stations on the longer courses, and mandatory equipment and self-sufficiency rules for the higher-distance formats. The weekend format stages starts across Friday, Saturday and Sunday with multiple wave starts per distance; some shuttle and nocturne start times are still marked "à venir" (to be announced) on the organiser pages and should be checked closer to race day. The event is presented as family-friendly with specific children’s and walking events alongside the competitive trail races.
