The Billère run is a small October running event held in Billère, located in the Pyrénées-Atlantiques department of southwest France. The event features very short races: children can compete in 400-meter or 800-meter races, and teams can participate in a 4.5 km relay.
The previous edition saw 99 participants, indicating it functions more as a local community race than a large road-running festival. The race distances are designed to be accessible for families, younger runners, and relay teams seeking a short race instead of a standard 5K or 10K.
