Most exciting news

From the very first PBBU, Mooirivier Beskerming became one of our regular sponsors. Always going above and beyond what we expect from a sponsor, Mooirivier Beskerming has a heart for local events and to sponsor local. We are thus very proud to anounce that MB has now become the offical name sponsor of the PBBU. Welcome to the Mooirivier Beskerming Potch Big Backyard Ultra! The Unicorn approves!

6.706 km | 4.167 miles

A backyard ultra is run on a trail which is exactly 6.706km or 4.167 miles long. This course is called a “yard”. Yards can consist of purely trail or a combination of trail and road.


Every hour on the hour

Runners have exactly one hour to complete a yard. A new yard starts every hour, exactly on the hour. With time left from an hour runners can rest, eat and recover. Runners not in the corral once the hour is up, are out.


One winner

There can be only one winner. A winner is declared if the last person standing can complete a full yard within the allotted time. The runner-up is then known as the “Assist”.



There is no end in a backyard ultra. The current PBBU record is 22 yards or 147,4km set by Nicky Booyens in April 2023. The current SA record is 37 yards. The world record is 101 yards or 677km!

So what do our runners think about the PBBU?

“My first ever PBBU and what an experience. Starting in the cold morning and ending in the heat of the day. Smashed my personal best (23km) by doing 7 yards(46.5km). The motivation from the pink unicorn and all the runners and supporters was really cool to experience. I will definitely be back and this time I want to end at midnight.”

Martin de Beer
7 yards

“I did my first PBBU in April 2023 and I loved it! It was a great course with a bit of everything – flats, climbing, downhills and very little technical running so it made it very runnable for everyone. The set-up, vibe and venue were perfect for a BYU and the water point treats were very very yummy! I will definitely come back for another one, thanks for a great event!”

Nicky Booyens
22 yards and current pbbu record holder

“The eager desire to continue running until I either run out of time or my legs quit, and to push my body further each time, started at PBBU! I’ve only been running for 3 years, and I’ve learned so much from running these events. One of the most important things that I took away from my last PBBU is trial and error and to learn from this. I will come back every time with the mindset to improve my previous yards and to be better than what I was previously. The best thing about PBBU is the community that it creates and to be part of that is special. Thanks for always making me believe I can go just one more yard!”

Nico Prinsloo

“It was a wild and wacky experience. Totally off the grid. Great support. Excellent organisation. Lovely surroundings. A totally uplifting and positive escapade.”

Most Backyard Ultras are won with between 20 and 30 yards, with low key grassroots events generally running from 12-24 hours. Being in Potch we are blessed with numerous superheroes able to push over the 24-hour barrier. Gear therefore is of utmost importance. Although there is no compulsory gear for this run we do suggest a few essentials…

So what would I need?


Although it might not seem like it, a backyard ultra does, in fact have a number of rules that must be adhered to. These are described by the founder of the backyard ultra format – Lazarus Lake – and is applied world-wide.

So what are the rules? Read more on backyardultra.com
