Trail d'Agen is a trail race held in late March in Agen, located in the Lot-et-Garonne department of southwest France. It provides two short trail options, 8.5 km and 16.5 km, positioning it within the discovery-trail category rather than the long mountain-ultra domain. Both distances are single-loop courses, featuring 250 m of elevation gain on the shorter route and 550 m on the longer one.
The race combines urban running with riverside paths along the Garonne River. Its descriptions mention culture, history, food, and a bridge or viaduct on the course. The 16.5 km option is the more frequently chosen distance, having previously attracted over 200 participants, while the 8.5 km race saw more than 100 runners. It appears to be a focused local event for participants seeking a genuine climb and trail experience without the commitment of an extended race.
