Trail'R Run - Treillières 2027

The Trail'R Run is a winter trail race held in Treillières, a commune north of Nantes, offering distances from 5 km to 35 km. It is organized by Treillières-Running-Urban-Nature, a local running club that also leads its members on paths and roads every Thursday evening and Sunday morning. The longer routes feature 13 km, 25 km, and 35 km circuits set through the countryside surrounding Treillières. This is a regional runners' event known for its muddy, wet, and tiring conditions: finishers are described as arriving soaked, often covered in mud, yet still pleased with their accomplishment.
