The Battersea Park Running Festival is a flat race day held at the Millennium Arena on Carriage Drive East in Battersea Park. It includes a marathon, a half marathon, and a 1km children's race, catering to both adults seeking a full marathon and families looking for a short run. Science in Sport presents the festival.
The marathon course consists of 11 laps within the park, and the half marathon uses 5 laps. Participants begin and conclude on the athletics track at the Millennium Arena. The children's race takes place entirely around the track. The course features flat loops and paths lined with trees, offering a suitable option for runners focused on achieving a personal best rather than tackling a challenging, hilly route.
