We are excited to continue with the latest instalment of the Limitless Trails BYU Series. This one has a time cut-off and a sprint last lap finish to determine the WINNER.

The first 11 yards are the standard format, each one to be completed within an hour. The 12th and final yard is a race! 

Trophies awarded to 1st, 2nd and 3rd place finishers.

Anyone completing a yard receives a medal, and we have a special medal for anyone who reaches 32 miles ie ULTRA.

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 watered and fed, with  delicious and nutritious hot and cold food.
