Les 30 km d’Arradon is a running race series in Arradon, featuring a main 30 km race and two other events. It has been held for at least 36 editions, with one edition attracting nearly a thousand participants across the three races.
The main race saw an unusual conclusion when Sébastien Le Cocq, who had a lead of over a minute entering the final kilometer, was misdirected by a course marshal. Christophe Olliero finished first and expressed surprise at not seeing Le Cocq ahead, while Le Cocq stated he did not hold the volunteer responsible and highlighted the significance of volunteers in race organization.
