Trails & Tarmac Backyard Ultra

The Trails & Tarmac Backyard Ultra is an endurance running event held near Crickhowell in the Black Mountains, Powys, UK. The race features a 4.167-mile loop combining 50% trail and 50% tarmac, with mostly flat terrain, one gradual climb, and a short steep section, designed for fast running. Participants run one loop every hour, starting precisely on the hour, continuing until only one runner remains.

Runners who reach 32 miles earn medals, and the last person standing receives the winner's trophy. The event offers aid stations, hot food after the fifth loop, medical support, showers, and toilets, creating a supportive atmosphere for ultra runners.
