The Cross Duathlon de Poulx is an off-road run-bike race held in Poulx, a village in the Gard department of France's Occitanie region. Nîmes Triathlon, also known as Crocos de Nîmes Triathlon, organizes the event, with recent listings placing it in March. The event features three race formats: a Kids race for ages 8-11, an XS race for ages 12 and up, and an S race for ages 16 and up. Participants can enter each format individually, and the Kids, XS, and S races also have relay options.
The course details divide into running and cycling segments. There are separate children's running courses, an XS running course, and a cycling course designated for the 8-11 age group. This setup makes it a suitable introductory cross-duathlon for young athletes and a short-format race day for older juniors and adults. The event's scheduling has faced recent uncertainty; the listed Jeunes, XS, and S editions are either not being held or are awaiting confirmation, and one scheduled race was canceled due to organizers deeming the weather too unpredictable, leading to full participant refunds.
