Color Run IAE Brest is a 5 km road race in Brest, Finistère, on the Brittany coast, typically held in late March. As a Color Run, the focus is on moving through a short course with color, music, and a relaxed atmosphere, rather than competitive racing.
The course is a 5 km loop divided into 2 km segments, making it suitable for beginners and experienced runners alike. This event supports Les SoeuRettes, an association that fights Rett syndrome. The atmosphere emphasizes solidarity, accessibility, and a festive conclusion over competition or personal records.
