Cast Hell Trail is a trail race in Finistère, Brittany, with origins in Cast and current race details locating it in Pleyben. It takes place in late September and provides two off-road distances: a 13 km trail and a 28 km option.
The 13 km race is the more popular option, with over 200 participants in the last edition, while the 28 km race had more than 100. The first edition was organized by Elan Du Porzay. The event is listed on Brittany’s running calendar as a local trail gathering, not a major city road race.
