THE RACE & HISTORY
Legends Backyard Belgium: find out where your limit is
From Tennessee To Belgium
The roots of the Backyard Ultra lie in the backyard of the legendary Lazarus Lake (Laz) in Tennessee. The concept is as simple as it is ruthless: run exactly 6,706 meters each time, within the hour, until only one runner remains.
The story of Legends Backyard Belgium began in 2020, in the middle of the COVID-19 pandemic, when we first organized the Belgian Sattelite of the Team World Championship. Our regular backyard was subsequently established in 2021. Where we started in Kasterlee at Domein De Hoge Rielen, we moved to a new home base in 2024: Domein Beverdonk in Retie.
A Ground for World Records
Our course at The Hoge Rielen was already known worldwide as a course that had everything to produce huge numbers, with Karel Sabbe breaking the World Record in 2020 with 75 loops & Ivo Steyaert & Merijn Geerts with 101 loops (#breaking100) in 2022.
And our course in Retie lived up to the huge expactations since our move. In 2024 Frank Gielen, Ivo Steyaert & Merijn Geerts set a new World Record with 110 loops. And while our “regular” backyard started a bit more modest, the last years we saw a phenomenal 116 (new WR in 2025) and 114 laps (2026) run by Lukasz Wrobel to take the win.
Ready to find your own limit
Our race practically guarantees that you will be able to go far… very far! We provide the perfect conditions for you to discover your true potential—you just have to bring the drive to run the loops.
So if you want to find out exactly how far you can go in a backyard, this is the ideal race!
Don’t wait any longer and register for the next edition of our event.
Do it now and you will find yourself at the starting line with some of the sports’ greatest athletes.
SILVER TICKET RACE
With a large part of the world’s elite at the starting line each time, Backyard Belgium is the perfect race to qualify for your national team or the prestigious individual World Championship in Tennessee.
But even better: in the years where this applies, we are an official Silver Ticket race for the Satellite Team World Championship for Team Belgium. This guarantees the winner a direct spot in Team Belgium if a Belgian wins, regardless of the number of loops. 2026 was such a year, but since a Belgian did not win (Lukasz Wrobel did) no silver ticket was awarded.
