Trail des Kaolins is a trail-running event held at the Salle omnisports in Quessoy, Côtes-d'Armor, Brittany. It typically takes place in early October, featuring off-road races on wooded paths. The main events are the 10 km La Kaoline and the 20 km SOKA, complemented by a 10 km walk and races for children and juniors.
The 10 km race is suitable for those seeking a moderate trail challenge, while the 20 km race offers a longer test on the same local terrain for more experienced runners. Youth races are included alongside adult distances, integrating families into the day's activities. On-site registration is available, contributing to a relaxed local atmosphere distinct from larger events requiring advance planning.
