Ultra-Trail Serra da Freita is a June trail-running series held in Arouca, within Portugal’s Aveiro district. Runners can choose from four mountain distances: 19 km, 31 km, 65 km, and 100 km, with the 100 km being the most popular. The event is part of the UTMB Index, allowing finishers to count it toward UTMB qualification and ranking.
The routes traverse Serra da Freita, utilizing forest and natural terrain instead of roads. The shorter distances offer accessibility for newer trail runners or those seeking a challenging day without an ultra commitment. The 65 km and 100 km races appeal to experienced mountain runners aiming for a long effort in northern Portugal.
