Infinity trail : île d'aix

The principle of the Infinity Trail is simple: it's the same as the Backyard Ultra:
A 6.7-kilometre lap to be completed in less than an hour.
Every hour a new start, until there is only one person left in the race.
The race can last 10 hours, 24 hours or even 102 hours to beat the world record - it's all up to YOU!

In short, you set your own limits, whether it's the distance of a marathon, a 100 km or even over 300 km!
