The Grand Raid des Pyrénées Tour des Cirques is a 124.8km alpine trail race held each August in the Hautes-Pyrénées, France, starting from Piau-Engaly with the event based in Vielle-Aure. The course covers approximately 7,000–7,500m of elevation gain — around 56m per kilometre — placing it in the more demanding third of DTR's database by elevation density. Entry costs €175, or €1.40 per kilometre.
The route traverses the Néouvielle natural reserve, Cirque de Barroude, and the highest passes of the central Pyrenees, descending through glacial lake terrain above 2,000m. The top single descent drops 1,588m over 11.34km — one of the 25 largest point-to-point descents in DTR's database — and it begins just 14km from the start. Average uphill gradient is 13.39% and just 11.8% of the course is flat terrain. Toulouse (TLS) is approximately 115 minutes away.
Registration is lottery-based and the Tour des Cirques sold out for 2026; the lottery closes in January each year. A qualifying race is required to enter. Founded in 2017, it suits experienced mountain runners who thrive on sustained descending, dramatic Pyrenean terrain, and events worth planning a year in advance.
