Lo Petit Aussalès

The Lo Petit Aussalés 2026 is a prominent mountain running event within the historic Challenge d'Ossau series, held in the heart of the Pyrénées-Atlantiques. Scheduled for Sunday, May 24, 2026, the race is organized by the Commune of Eaux-Bonnes. Known as the "Return to the Roots" edition, the course takes runners through high-altitude pastures and dense forests, offering a significant vertical challenge starting and ending at the iconic Eaux-Bonnes Casino.

Event Logistics and Participant Information:

• -- The Course Route: The main race begins with a relatively flat 400m "horizontal promenade" before entering the Assouste woods. The real difficulty begins at the 5km mark at the Balourd path junction, leading into a steep ascent.
• -- Peak Elevation: The highest point is reached at the Pas de Brèque (1,865m) at km 10.6, following passage through the Quebotte woods. This is followed by a technical descent toward the Lacarret cabin.
• -- Trail Integration: Much of the return journey utilizes the GRP (Grand Randonnée de Pays) of the Ossau Valley tour, leading participants back down to the Casino.
• -- Organization: The race is part of the Challenge d'Ossau, which includes other prestigious regional races such as the Trail du Bénou and the montée de l'Aubisque.
• -- Registration: Sign-ups are managed via the Eaux-Bonnes animation department. Digital GPX files are provided for navigation, though the course is fully marked on race day.

Regional Context and Environment:

• -- Location: Eaux-Bonnes is a historic thermal spa village in the Vallée d'Ossau, Bearn. The village is nestled at 757m altitude, serving as a gateway to the high Pyrenean peaks.
• -- Terrain: Expect a mix of forest trails, rocky ridge paths, and mountain pastures (estives). The terrain is typical of the High Bearn—lush and green but potentially technical and steep.
• -- Climate: Late May in the Pyrenees is a transitional period. While spring is in full bloom in the valley, residual snow patches can sometimes be found near the Pas de Brèque (nearly 1,900m). Rapid weather shifts are common in this alpine environment.
• -- Atmosphere: Lo Petit Aussalés is cherished for its authentic mountain spirit, often serving as a key testing ground for local runners participating in the full Ossau Challenge circuit.

The Lo Petit Aussalés 2026 provides a pure skyrunning-style experience, combining the nineteenth-century charm of a spa town with the raw, vertical challenges of the Ossau Valley.
