24H de P

24H de P is a long-distance endurance running event in Santa Maria da Feira, Portugal, centered on continuous running on an endurance circuit. The primary event is a 24-hour challenge for solo runners aiming to keep moving for a full day. The event also provides a 24-hour relay for teams of four, a 12-hour race, a 3-hour race, and a night marathon. It takes place over a September weekend and is designed for runners seeking a time-based test instead of a standard point-to-point road race. The format makes the race as much about pacing, fueling, sleep management, and mental fortitude as raw speed. Participants can opt for a full-day solo effort, share the 24 hours with teammates, or select one of the shorter options. Consequently, the field can accommodate seasoned ultra runners alongside athletes beginning endurance racing with a more accessible distance. Clube de Atletismo de Lamas organizes the event, with assistance from the Santa Maria da Feira City Council. This is the fourth edition of the race.
