Trail des Cadoles is a small nature running series in Saône-et-Loire, eastern France. All races begin and end at the Château de Brancion, near Tournus. Participants can select from distances of 6 km, 11 km, 18 km, and 27 km, suitable for both new trail runners and those seeking a longer evening run on country paths.
The courses traverse the hills of the Tournugeois, an area with vineyards, villages, and forested ridges surrounding Tournus. Asso Trail Tournus organizes the event. The château location also restricts participation, with a cap of 500 runners, maintaining its character as a local trail gathering rather than a large-scale event.
