Gwern ar Sec'h Gravel - Rennes

Gwern ar Sec'h Gravel is a 50 km gravel cycling ride based in Rennes, Ille-et-Vilaine, France. It is listed as a rando gravel event, meaning the format is closer to an organized off-road ride than a road race or a closed-course competition. The listed distance is a single 50 km Gravel option, starting in the morning, with a modest entry fee. The event drew 110 registered participants in its previous edition, indicating a small local field rather than a large festival-style gravel weekend.
