The Cow Shed Backyard Ultra

The Cow Shed Backyard Ultra, held at Wheelbirks Parlour on Wheelbirks Farm in Stocksfield, Northumberland, is Greener Miles Running’s eco-conscious ultra, in the Big’s Backyard Ultra format. Competitors must complete a 4.1-mile loop every hour, with the bell rung on the hour until only one runner remains. Each loop climbs about 550 feet, across farmland, single-track, and woodland dirt tracks on private land not recce-able beforehand.

New for 2025 is a five-person team option; prizes for the last person and last team standing. The event includes on-site catering, camping, fully waymarked routes, a bespoke eco memento, and green initiatives. Visit the organization's website for the most recent information.
