Val d'Aran by UTMB 55km: Top1 Descent Rank 39/390, Colomèrs Glacial Lake Cirque, and 4 UTMB Running Stones in the Only Spanish Territory Facing the Atlantic

Q: What makes the Val d'Aran by UTMB 55km technically demanding from a descent perspective? A: The PDA 55km has the 39th deepest single descent of 390 European trail races — a 1,114m drop at -19.88% average gradient, which is near 1:5 grade and among the most extreme single-descent gradients in the European database. Average downhill gradient ranks 342nd of 390 (INVERTED: only 48 races descend more steeply on average). With official D- of 3,700m exceeding D+ of 3,300m by 400m, the course descends more than it climbs. Just 9.45% of terrain is flat (rank 113/390 = fairly mountainous). The combination of a near-1:5 single descent, steep average descents throughout, and more total descent than ascent makes the PDA one of the most technically demanding 55km downhill profiles in European trail running.

Q: What is Colomèrs and why does the PDA course go there? A: Colomèrs is the largest glacial lake cirque in the Pyrenees — a high-altitude basin shaped by ancient glaciers, containing over 20 lakes at elevations above 2,000m within the Aigüestortes i Estany de Sant Maurici National Park and its surrounding protected area. The course name PDA stands for 'Peades d'Aigua' in Aranese — the regional Gascon Occitan language of the Val d'Aran — which translates as 'Footsteps of Water,' directly referencing the lake cirque landscape that defines the route. The 1,247m single ascent (top1 ascent rank 85/390) climbs to this lake basin before the main descent sequence. Running through Colomèrs is what distinguishes the PDA from other UTMB World Series 50km-category races in Spain.

Q: How does the Val d'Aran by UTMB 55km qualify for UTMB Chamonix? A: The PDA 55km is classified as a UTMB World Series race in the 50km category, awarding 4 Running Stones. UTMB Running Stones are the qualification currency for the UTMB Chamonix finals — runners accumulate Stones across World Series races to access the main UTMB event. At 4 Running Stones per finish, the PDA is among the higher-value 50km-category qualifiers in the World Series. The race has been sold out every year since its inaugural 2021 edition. For 2027 qualification, check registration timelines at valdaran.utmb.world — previous editions have required early registration to secure a place. Maximum race time is 14 hours.

Q: What is the Val d'Aran and why is it unique in Spain? A: The Val d'Aran is a valley in the Pyrenees that occupies the north-facing (Atlantic) slope of the mountain range — making it the only territory in Spain that faces the Atlantic rather than the Mediterranean. As a result, it has a wetter, greener climate than the rest of Catalonia and Spain, and culturally it has its own language: Aranese, a variety of Gascon Occitan that is co-official with Catalan and Spanish. The valley is governed autonomously by the Conselh Generau d'Aran. Vielha is the capital. The proximity to Aigüestortes National Park gives the race access to some of the most protected and scenically extraordinary terrain in Spain.
