La Casartelli

Nestled in the heart of France's Pyrenees Mountains, St. Girons plays host to an exhilarating endurance challenge known as La Casartelli on September 6, 2026. This annual event offers runners a unique opportunity to experience some of the most breathtaking landscapes and challenging terrain that this region has to offer.
The centerpiece of the day is the grueling La Casartelli race, which spans an impressive distance of 147 kilometers with nearly 3,000 meters of elevation gain. This route winds through a series of steep climbs and descents, testing both physical endurance and mental fortitude as participants navigate rugged mountain paths.
For those seeking a slightly less daunting challenge but still desiring to push their limits, La Découverte presents an 87-kilometer course that ascends over 1,400 meters. This race offers a scenic route through picturesque valleys and up into the mountains, providing runners with stunning views of rolling hills and dense forests.
Both races are designed not only to challenge participants physically but also to immerse them in the rich natural beauty of St. Girons and its surroundings. The event is meticulously organized by local enthusiasts who bring together a community of athletes from around the world for an unforgettable day of competition, camaraderie, and celebration.
In addition to these long-distance races, La Casartelli also welcomes cyclists with La Marco and La Marco VAE, each covering 87 kilometers but tailored differently. The traditional La Marco route is a thrilling mountain bike ride that mirrors the terrain challenges faced by runners in their longer distances. Meanwhile, La Marco VAE offers an electric-assisted bicycle option for those looking to explore similar landscapes without the intense physical demands.
Each race promises not just a test of athletic prowess but also a deep connection with nature and community. The event is set against the backdrop of St. Girons' charming streets and mountain trails, making it a must-attend destination for endurance sports enthusiasts in 2026.
This unique blend of challenging courses and scenic routes ensures that La Casartelli remains one of the most anticipated events on the global race calendar each year.
