Trilhos do Paleozóico

Trilhos do Paleozóico begins and ends at Largo do Centenário in Valongo, near Porto, northern Portugal. This mid-March trail running event offers four race distances: 12 km, 23 km, 36 km, and 48 km, alongside a 12 km walk. The 48 km Ultra Trilho Paleozóico is the main event and the most popular choice, with shorter races and the walk catering to participants of varying experience levels. The routes traverse trails and mountain paths in the Serra de Santa Justa, Serra da Pia, and Serra do Castiçal. These paths include forest sections, natural terrain, and geological formations within the Paleozóico Park of Valongo. The event connects with the Valongo Trail Center, establishing it as part of a local trail-running hub. Participation is divided by distance and category, covering walking, shorter races, longer trail races, ultra-distance running, and children's events, all featuring electronic timing and live results.
