Ultra Maratona Atlântica

Ultra Maratona Atlântica is a trail running race in Comporta, Portugal, typically held in late July. Participants select either a 10 km loop or a 45 km loop, both designed around sand and seaside terrain instead of roads. The race guides participants onto the fine sand of the Portuguese coast, with the ocean nearby, making the waves a feature of the day. The course is straightforward yet challenging: one loop for each distance, with the longer option requiring runners to manage 45 km on soft coastal surfaces. The location also facilitates extending the visit, with Alcácer do Sal, the Sado Estuary Nature Reserve, Setúbal vineyards, and Comporta’s beaches commonly suggested as post-race activities. Following the run, meals frequently feature local products instead of typical race fare.
