No finish. No time limit.
Only the next loop.
The Last Soul Ultra is a backyard ultra: everyone starts together, every hour, on the hour. If you don’t make it back from the 6.706 kilometers in time, you’re out. There are no placements — the winner is the one who completes one more loop than everyone else. No on-site crowd, but a round-the-clock livestream. A format that doesn’t ask who’s fastest, but who can endure the longest.

After 34 laps
Pierre ran the Last Soul Ultra. 34 laps, around 228 kilometers, two nights. Then it was over — not because his legs gave out, but because he stopped when it was his decision.
He didn’t reach the goal he had set for himself. But he made the right call. He left the course upright and uninjured. That’s also resilience: knowing when.
I’m not disappointed. Not for a second. — Pierre Biege, ultra runner & Joe Nimble athlete

2025 and the 41st loop
Last year, Pierre’s race ended in the 41st loop: he fell asleep while running.
40 loops, about 268 kilometers. He spent an entire year working on everything
that stopped him then. This year, he’s going in with a clear goal:
75 loops. Around 500 kilometers. Nearly double.
The Last Soul Ultra isn’t a race I have to win. My limit isn’t in my legs: the next day I need to be able to take my three daughters to the playground. I won’t do anything that jeopardizes that. -Pierre Biege, ultra runner & Joe Nimble athlete
The run in three chapters
150 runners, one mass start, every hour from the beginning.
When the field thins out and the head decides, not the legs.
It’s not the fastest who wins.
The one who stays does.
Pierre has several pairs ready, switching based on section and weather. He mainly runs the Addict Flow 2 on the fast, flat stretches and the Trail Addict Flow+ as soon as it gets rough. Two shoes built for distances others consider impossible.
