The Cross Guy Dalban is a cross-country race held in Firminy, taking place in the Parc des Bruneaux on grass and park paths that can become muddy. ACO Firminy is the organizer. The event is structured by age and category: youth races cover approximately 2 km, senior women about 6 km, senior men about 8 km, and a popular adult race ranges from 6 to 6.8 km.
This is a long-standing local cross-country event with a regional designation. Recent editions have attracted around four hundred participants. The format is straightforward: runners complete laps or follow marked sections within the park, and spectators can observe without charge. This arrangement lends the day more of a club cross-country meeting atmosphere than a road-race festival.
