Organiser's Description

Back by popular demand!

Orkney Athletic and Running Club are delighted to be putting  on a second edition of Orkney Backyard Ultra!

Will you be the last still going in Twatt?

4.1667 miles on the hour, every hour. It's a race without ending, a chance to push yourself to see how long you can keep going!


This event is an affiliated BYU if you run enough laps and you could get on the "At-large list" for Big's backyard in Tennessee 2023.


Our Backyard is on Twatt Farm in the west of the very beautiful main island of Orkney. Closer to Oslo than we are to London, Twatt is the perfect place to run and run and run – and run. It’ll hurt. But in a good way.


This low-key, off-grid event will be run on a mixed terrain route of dirt road, grass and trail - out and back - across Twatt Farm.  With almost 300ft of elevation, the route is easily completed within an hour (at least for the first few laps!)


Runners must be inside the starting Coral when the farmer honks his tractor horn to signal the beginning of every lap – on the hour, every hour from midday on Saturday 8th July 2023. Anyone who doesn’t line-up for the start at any point during the race will be timed out and awarded for their efforts with a lovely unique medal and goody bag.


Any proceeds from our Backyard will go to Orkney Athletic and Running Club to support our island based athletes.
