La Cursa del Tractor is a running race in Casserres, Barcelona area, where runners try to stay ahead of a tractor. The main race covers 12 kilometers, divided into one-kilometer laps. A three-minute break occurs after each lap before the next round begins. If a tractor catches a runner, that runner is eliminated. The winner is the first person to complete the twelfth lap.
Additionally, a shorter 3 km option is available, catering to participants not seeking the full tractor chase. This format distinguishes the race from a standard road run, as pacing is influenced by repeated starts, brief rests, and the threat of being caught. It is a recognized local race on the Barcelona running calendar, with its tractor rule providing a distinct identity beyond just distance and location.
