Trail de la galette - Mantes-la-Jolie 2027

The Trail de la galette is a 12 km discovery trail race in Mantes-la-Jolie, Yvelines, held in January with an evening start at 18:30. It is a short-format trail, not a long mountain outing, featuring 150 meters of climbing and a modest bib price of 15 EUR. The course details suggest an accessible local race: enough elevation to feel like trail running, but not so much that it excludes newer participants. The Mantes-la-Jolie city hall organizes it, and a recent edition had 784 participants, indicating a substantial field for a town race without the feel of a major mass event.
