Boucle infinie O2 L'air

Boucle Infinie O2 L'Air invites runners to the picturesque village of Plourivo on April 23, 2027. The race begins at noon and continues around the clock until only one runner remains or until a set limit is reached on Sunday, April 25, 2027.
The course features a 6.7-kilometer loop that participants must complete every hour to stay in contention. Each lap takes place over a period of 60 minutes; runners who finish within this time frame have the opportunity to rest and refuel before starting their next lap at the top of each hour. Should a runner fail to complete an entire lap within 60 minutes or miss a start, they are eliminated from competition.
The event culminates with one final loop beginning at 5 PM on April 25th when only a few runners remain. The last participants will have exactly 60 minutes to finish the course, and in case of multiple finishers, victory is awarded based on the fastest time recorded during this concluding lap.
Proceeds from Boucle Infinie O2 L'Air support the charity organization O2 L'air, which focuses on fighting cystic fibrosis. The entry fee for runners stands at €80, covering race bibs, hydration and food stations along the route, as well as a commemorative gift upon completion or withdrawal.
With only 95 spots available exclusively to adults, this endurance challenge offers an unparalleled opportunity to push personal limits while contributing to a worthy cause.
