Ekiden du PAAC is a road race in Pontault-Combault centered on an Ekiden, a team relay covering the full marathon distance of 42.195 km. The relay begins after shorter events, with 5 km, 10 km, and 12 km Nordic walking also offered.
The relay format is the main attraction: participants can form teams with friends or family and divide the marathon distance rather than completing it individually. The event also offers prizes for rankings and records, posts results on race day, and publishes them online shortly after.
