The Cross Duathlon des Coteaux Sézannais is an off-road run-bike-run event held in Sézanne, within the Coteaux Sézannais region of France. Participants can choose between two primary race distances: the S-distance cross duathlon and the M-distance cross duathlon.
The S race is designed for individual competitors. The M race accommodates both solo athletes and relay teams. This structure caters to a range of participants, from those seeking to complete the entire duathlon independently to teams preferring to divide the longer course.
