Trails & Tarmac Back Yard Ultra

Friday 19th September 2025

We are excited to continue with the latest instalment of the Limitless Trails BYU Series. With a little twist to the rules.

We intend to give medals to anyone who reaches 32 miles ie ULTRA, the last person standing will be allocated the winner's TROPHY.

Set just outside Crickhowell deep in the Black Mountains the route is 50/50 Trail and Tarmac, with only one gradual climb and a short steep section, the rest is relatively flat terrain which means fast.

You will be fed & watered, with additional hot food after the 5th yard.
