Trail la Perbaisienne is a small nature-trail event in Trentels, with bib pickup and the start at the Salle des Fêtes. It is organized by Perbais Trentels / APTL, the association linked to the Perbais-Trentels-Ladignac twinning, and it is the first trail race put on in the commune. Runners can choose a timed 8 km race with 150 m of climbing or a timed 15 km race with 350 m of climbing, while walkers have a non-timed 8 km hike.
The routes are described as countryside trails with short climbs rather than flat road running. The longer race starts first, followed by the shorter trail and then the hike. Two aid stations are planned out on the courses, and the finish area keeps the local feel: pizza, quiche, dessert, drinks, and a refreshment stand with beer from the Zebullin brewery. The first three men and women in each race receive prizes, including vouchers for Running Le Passage d'Agen.
