[A CONFIRMER] Trail du Pays de Sully - 17 km MN 2026

The Trail du Pays de Sully begins at Ecole des Baronnes in Rosny-sur-Seine, west of Paris, directing participants into the forest on trail courses of 11 km, 19 km, and 31 km. A 15 km walking option is also available. The longer races commence first in the morning, with the walk and the shortest run following, structuring the day around multiple distances rather than a single main field. All routes traverse forest paths and trails, featuring elevation gains from +300 m on the 11 km course up to +800 m on the 31 km course. The 19 km loop includes one aid station, the 31 km loop has two, and the 11 km course has none, making water carriage essential; runners must also provide their own cup or container at aid stations. Poles are permitted, the participant limit is 600, and the 31 km race has a 3h30 cutoff at the second aid station near kilometer 21.
