Embark on a unique, mysterious, and self-supported trail adventure at the Barklauch in the Bois d'Auch on Friday, March 20, 2026. This unconventional event challenges participants to complete up to five 15km loops, with the exact course and the locations of ten hidden books revealed only at 5:00 PM, just one hour before the 6:00 PM start. Each runner must find and tear out the page corresponding to their bib number as proof of completion, with a strict 2.5-hour time limit per loop to continue.
With no official ranking or prizes, the focus is purely on the fun, challenge, and camaraderie of navigating the woods by night with only a map, compass, and personal fortitude. Entry is limited to the first 30 respondents via email, requiring a small fee and a symbolic magnet from your hometown. Prepare for a truly grassroots, adventurous, and ethically-minded run where discovery and personal resilience are the only rewards.
