The Trail de la Vallée du Rodo is a trail race held in Pordic and the village of Tréméloir, Côtes-d'Armor, Brittany, each September. It takes place on the third Sunday of the month and offers three distances: 9 km, 14 km, and 23 km. The objective is to guide runners along paths, minimizing their time on asphalt. The shortest race is suitable for beginners, while the longer routes present a challenge for experienced trail runners.
The routes trace the Rodo, Camet, and Ic rivers through the valleys near Tréméloir and Pordic, favoring technical trails over simple road sections. Tréméloir Sports Nature organizes the event, which originated from a group of friends involved in running and mountain biking who aimed to create a sporting and festive occasion for the village. Volunteers prepare the race village and mark the courses, attracting both novice and seasoned participants. The event also contributes to a charitable cause.
