Trail in Chartres en Lumières

The night sky over Eure-et-Loir will ignite with athletic energy on Saturday, April 11, 2026, as the Trail in Chartres en Lumières makes its grand return. Organized by C'Chartres Métropole Triathlon, this glowing spectacle serves as the official launch for the "Chartres en Lumières 2026" season. Thousands of participants will weave through the historic streets of the city center and the lower town, passing under the dazzling projections and light installations that have made Chartres a global destination for urban illumination. Starting and finishing near the iconic Colisée, the event transforms a standard footrace into a luminous journey through history and art, lit by the bobbing beams of mandatory headlamps.

The evening is meticulously structured to accommodate every member of the regional athletic tribe, from budding "Eveil Athlétique" sprinters to seasoned endurance enthusiasts. The main 10km trail challenge features a dynamic course with over 120 meters of elevation gain, circling the Colisée and diving into the atmospheric alleys of the city. For those who prefer a less competitive pace, the walking division offers the same light-drenched views without the pressure of the clock. With a strict cap of 2,000 runners for the main event and no on-site registrations, the festival maintains an intimate yet high-energy atmosphere, ensuring that every participant can safely experience the "magic of the light" before the final cut-off.
