Last Soul Ultra 2026: Mark Dowdle Sets New German Backyard Ultra Record After 94 Hours

He had never been to Germany before. He landed with 15 minutes to spare, on a chartered private jet he''d booked in a panic after his commercial flight was delayed. Ninety-four hours later, Mark Dowdle was still running — and he had just set a new backyard ultra record on German soil.

What Actually Happened

At the 2026 Last Soul Ultra in Bornheim, near Cologne, Dowdle covered roughly 630 kilometres — about 94 hours of running, one loop after another, with almost no sleep. It's the best-known backyard ultra performance ever recorded on German soil, four laps beyond the previous mark of 90, set by Merijn Geerts in Rettert back in 2022.

The Format: Nowhere to Hide

Last Soul Ultra follows the backyard ultra format, invented in 2011 by American ultrarunner Gary Cantrell. The rules are brutally simple: every runner starts together on a fixed loop — here, 6.7 kilometres — and must return to the starting corral before the next hour begins. Fall short, even by a second, and you're out. The race doesn't stop for darkness, exhaustion or injury. It only stops when exactly one person is left standing, and even then, that final athlete must complete one more solo loop alone to be officially declared the winner.

There's no course map published, no fixed finish time, and at Last Soul Ultra specifically, no spectators at all — competitors are allowed up to three crew members in a small base camp, nothing more.

The 93-Hour Duel

Of the 169 athletes who started, the race eventually narrowed to two: Dowdle and German runner Ayyoub "Ello" El Osrouti. The pair matched each other hour for hour through three full nights, walking longer and longer stretches through the final morning but still making the bell every single time. El Osrouti eventually had to stop at 93 completed loops — the second-best backyard performance ever by a German athlete, behind only Hendrik Boury's 100-loop national record set at Big's Backyard Ultra in 2025. Dowdle continued alone for one final loop to claim the win.

A Race Built to Be Watched From Home

Last Soul Ultra was co-founded by German ultrarunner and content creator Kim Gottwald, together with former World Cup winner André Schürrle. What began as an experimental event in 2025 — Gottwald himself won the first edition, running 448 kilometres in 67 hours — has grown into one of the most-watched backyard ultras in the German-speaking world, drawing more than 40,000 concurrent livestream viewers at times. The organizers deliberately keep the venue secret and admit no crowd; instead, the entire race streams live and continuously on YouTube and Twitch, with additional updates on Instagram.

Entry isn't open registration either — spots are limited, and athletes are selected by application rather than a simple lottery.

Daily Chore Take

There's a genuine lesson buried in the chaos of Dowdle's arrival: the physical performance gets all the attention, but showing up ready to compete — even after a stressful, sleep-disrupted scramble across an ocean — is its own kind of endurance test. Backyard ultras strip racing down to almost nothing but repetition and refusal to stop; Dowdle's story is a reminder that the mental preparation to handle chaos can matter just as much as the training block behind it.
