The Red Dirt Backyard Ultra is Karratha’s unique take on a backyard ultra, held at Balmoral Road Caravan Park starting on Saturday 5 July 2025 until the Last One Standing.


A backyard ultra is a form of ultramarathon set around a 6.71km loop (or yard as it is known in the Backyard Ultra world), where participants run a loop on the hour, every hour for an unlimited amount of time. They stop for food and rest only in the spare time before starting the next loop and continue until there is only one participant left – known as the Last One Standing (LOS). Everyone else is deemed a DNF or Did Not Finish.


The Red Dirt Backyard Ultra is now an official backyard ultra, meaning there is no time cap and the event will continue so long as there is two runners left. This also means that teams won't be an option for the event, so why not come down and see how many yards you can push yourself to complete on your own.

Important documents: Before signing up to the RDBU please ensure that you read the Red Dirt Backyard Ultra 2025 Manual and Rules and Red Dirt Backyard Ultra Safety Briefing for Competitors and Volunteers (found below).

RED DIRT BACKYARD Safety Briefing for Competitors and Volunteers

Coming from Out of Town? 

Are you from out of town and would like to sign up to the Red Dirt Backyard Ultra but have no idea about accommodation, shops, eating places and where's the best place to get all of those last minute supplies? We have you covered. We do also have a range of basic supplies such as reclining camp chairs, tables, stretchers and more that we will be able to supply on a limited basis so get in contact if you would like more information. 

Backyard Ultra Podcast 

David Patterson or Patto as he is better known, has been interviewing all the big names involved in Backyard Ultras since September 25 2022. Competitors, run directors and crews have all had the opportunity to have a candid chat about all things Backyard Ultras. It is well worth a listen for hints, tips and ideas to take your next run to the next level. All episodes can be found on your favourite streaming service.

Hints and Tips:

Get out on the course! There will be opportunities to join with Pilbara Trailblazers to train on the RDBU loop, setting off on the hour for one or multiple loops to practice the event conditions.

Volunteers we need you! Not keen on running but don’t want to miss out on the epic adventure that is the RDBU? Lucky for you, we need volunteers. There are loads of different roles that need filling from set up and pack down, to manning the aid station, first aiders, tail runners/walkers/riders, and selling food and drinks. All volunteers get a voucher (TBD) and that warm fuzzy feeling you get from being a good egg. Volunteers will also receive 10% off entries to the Karratha Trail Adventures event, which is additional to the 10% that you get for being a Pilbara Trailblazers member.
