LACOSTOTRAIL

Lacostotrail is an exhilarating running event that takes place between Vernet d'Ariège and Bonnac, winding through the picturesque forests of Vernetois and Bonnacois. The race features two distinct courses designed to challenge runners with varying levels of experience: "Le Baron," a 16.5km trek with 500 meters of elevation gain; and "Le Galopin," a shorter but no less demanding route at 9 kilometers, boasting 250 meters of ascent.
Both routes require participants to be well-prepared for the unique demands of trail running in challenging terrain under the cover of night. Runners must possess endurance, agility, and adaptability as they navigate through rugged paths illuminated only by starlight or headlamps. The event offers a free-form pace with no time limits, allowing runners to set their own rhythm.
A new addition for 2026 is the introduction of team competition, where pairs can join forces on either course: one runner tackling "Le Baron" while another takes on "Le Galopin." This collaborative format results in a single overall ranking based solely on combined times, fostering camaraderie and strategic planning among participants.
The setting provides an enchanting backdrop with the serene beauty of the forest at night, offering runners a unique sensory experience as they traverse through nature's quietude under moonlit skies.
Lacostotrail promises to be not just a race but also a memorable journey for trail running enthusiasts looking to test their limits and explore the stunning landscapes of Vernet d'Ariège and Bonnac.
