Blocks League Lille is a night road race held in Lille, France, taking place within a stadium instead of a lengthy city course. It is a stage of the Blocks League national tour, with other events in Paris and Marseille. Participants can choose between a 3 km solo sprint and an 8 km team event. The Lille race typically occurs in mid-April and welcomes runners of all abilities. Its format emphasizes speed, quick accelerations, and direct qualification over consistent point accumulation.
The 8 km race features mixed-gender teams of five, completing 10 laps of 800 metres. The top six teams qualify for the grand finale. The 3 km race is an individual sprint where the top 10 men and top 10 women secure a "Pole Position," granting them an invitation and priority start for the finale. Nike is associated with the event. The venue also transforms into a social gathering space, featuring DJ sets, a partner village, a food court, and an after-party.
