Course organisée par la FFB 28 - 4 Octobre 2026

The Bâti’Run is a 100% Building race organized by FFB Eure-et-Loir, aiming to highlight professions and professionals in the building sector. It's also a solidarity race, with proceeds going to the League against Cancer as part of Pink October. The event will take place on October 4, 2026, starting from L'Illiade, the Chartres Expo park. The course is a nature trail, with 80% of it on paths, leading through the forest areas of Gasville-Oisème before reaching Saint Prest and Champhol. New for 2026 are a timed 6km race and a family-friendly 6km walk. The event also features a 12km race and a 12km Nordic walk, as well as free children's races. The 12km race includes a refreshment stop mid-course, while all timed race participants receive a finisher's medal and gift.
