Trail AiróRun is a trail running event in Airó, a parish of Barcelos in northern Portugal. Runners can choose 22 km or 14 km races, and there is also a 10 km walk for those who want the same natural setting without racing.
The routes use natural trails around Airó, with technical sections and demanding elevation changes rather than flat road running. The AiróRun team organizes the event, emphasizing the local feel: it draws trail runners, walkers, and community supporters into a regional off-road race built around the parish’s terrain.
