The CBA Race Cross Duathlon de Blanquefort takes participants into the Tanaïs forest, featuring a run-bike-run format. This cross duathlon focuses on off-road running and mountain biking, distinct from road racing, with staggered starts for different age groups.
The event welcomes non-licensed participants, increasing accessibility compared to federation-exclusive races. It offers Nouvelle-Aquitaine Championship titles for categories U15 to Masters, and youth races contribute to the Triathlon Schools Challenge. Online registration is the sole method for signing up.
