T-Rail de Mensignac is a trail race held in Mensignac, a village in Dordogne, Nouvelle-Aquitaine, France. It begins in the late afternoon near the end of April. The main events are short and accessible: adult trail distances are listed around 9-10 km and 15-16 km, with the longer distance attracting the most participants. Recent fields have numbered in the low hundreds, with one record showing just over 200 registered runners.
The organiser describes the route as unusual, short, and not very challenging, featuring modest elevation gains of about 130 m for the shorter race and 180 m for the longer one. The event also features children's races of 500 m and 1 km, giving it the feel of a local community gathering rather than a major destination event. Entry fees benefit the schools in Mensignac, and past results indicate both solo and relay options were available in earlier editions.
