Portland Pig Backyard Ultra

The Portland Pig Backyard Ultra is a timed lapped ultramarathon held at Grove Farm Estate, Portland, Dorset. The format requires competitors to complete a lap of 6,706 metres (4.167 miles) in under one hour, starting a new lap on the hour and repeating until one runner remains.

The route mixes surfaces including grass, gravel, track, tarmac and pavement and passes local features such as two prisons, a set of Olympic rings, a cricket club, two stone quarries with carvings, an Olympic sailing venue, coastal views, a wallaby farm, alpacas, Portland sheep and 19th century high-angle batteries.

Entries include a fully marked route, camping on site for the entrant and two crew (motorhomes allowed, no caravans), full chip timing and medic cover. Hot and cold water and toilets are provided on site; runners must bring their own food and be self-sufficient. Camping pitches do not have electric hook-ups. Outside assistance of any kind is not permitted and running or walking poles are not allowed. Open wood-burning fire pits are prohibited.

A DNF medal is provided for those who do not finish. The winner receives a bespoke memento carved from Portland stone. Age restrictions follow UK Athletics rules: competitors must be 20 or over to race beyond 45 km; ages 18 to 19 may run up to 45 km. Visit the organization's website for the most recent information.
