24H of P

24H de P is an endurance running event in Santa Maria da Feira, Portugal, structured around time-based challenges instead of a set road-race distance. Participants can choose to run the full 24-hour race solo, form a four-person team for the 24-hour duration, compete in a 12-hour race, a 3-hour race, or participate in a night marathon. The event is designed for endurance runners in senior and veteran categories, welcoming both individual athletes and teams. Organized by Clube de Atletismo de Lamas and the Câmara Municipal de Santa Maria da Feira, the variety of formats allows serious ultra runners, relay teams, and those preferring shorter distances to compete during the same race weekend.
