The Birell 10K Night Race Prague is a 10 km road race held in central Prague after dark, typically in September. It draws a large, international field of approximately 8,500 participants, catering to both elite athletes aiming for fast times and recreational runners seeking a city-night race experience. The course is flat, straight, and designed for speed, evidenced by the men's and women's records of 27:02 and 29:43.
Runners begin at Republic Square, passing historic streets and landmarks, following the Vltava River, and seeing Štvanice Island before crossing Čechův Bridge and Štefánikův Bridge in the city center. Live music, spectators, and entertainment along the route contribute to a street-event atmosphere. The race provides standard amenities for runners, including marked roads, hydration stations, timing chips, awards, refreshments, and post-race social activities.
