STE - CARAVELA Seguros Sintra Trail X'treme is a trail race held in September in Portugal. It begins at 8:00 in Lisboa's Zona Sul and proceeds towards Sintra. Participants can select from three distances: the X'perience 13 km, the X'plore 23 km, and the X'treme 33 km. The course travels from Lisbon's south side towards Sintra. The available distances accommodate both shorter-distance trail runners and those seeking a longer run. Entry is limited: 150 spots for the 33 km, 100 for the 23 km, and 150 for the 13 km. STE organizes the race, CARAVELA Seguros is the sponsor, and September weather typically features sunshine with cooler mornings before the day's heat.
