Trails & Tarmac Backyard Ultra

Trails & Tarmac Backyard Ultra – Winter, organized by Limitless Trails, takes place near Crickhowell in the Black Mountains, Powys (GB). A 4.167-mile loop blends trail and tarmac, with one gradual climb and a short steep section; the rest is relatively flat for speed. Backyard Ultra rules apply: each loop must be completed within an hour, with the next loop starting an hour after the last; the race is open-ended, continuing until only one runner finishes.

The winner is the last to finish a loop; medals are awarded to anyone reaching 32 miles, and the overall winner receives a trophy. On-site medics, showers, toilets, and hot food after the fifth loop enhance the experience. Visit the organization's website for the most recent information.
