What if you experienced running differently?
A.S.O. is launching a brand-new team running event — intense, committed, and boldly collective.
A completely new concept, simple in its rules… yet powerful in its experience.
The concept:
-
A looped course, combining road and trail
-
24 hours non-stop
-
Just outside Paris
-
Teams of 4, 6 or 8 runners
-
One single goal: cover as much distance as possible in relay, with your team
But these 24 hours aren’t only lived out on the course.
Between relays, it’s all about camp life:
-
A bivouac to recover and refuel before heading back out stronger
-
A central base camp with a warm, festival-like atmosphere — entertainment, concerts, shared moments… everything you need to eat, feel the buzz and keep the energy going, day and night
Here, there is no individual ranking.
What matters is cohesion, strategy, effort management, nighttime relays, and the energy you pass on to each other, hour after hour.
At the end of the 24 hours, there is just one finish line:
that of a collective human adventure, lived and celebrated together.
More details coming very soon.
