Trails & Tarmac Back Yard Ultra - Winter

About the Event

Dive into an exhilarating adventure with the Limitless Trails BYU Series, where tradition meets innovation on the rugged terrain of the Black Mountains near Crickhowell. This unique race challenges participants to navigate a 4.2-mile loop that seamlessly blends trail and tarmac in equal measure, offering runners both scenic beauty and fast-paced sections.
The course features minimal elevation changes, with just one gentle incline and a brief steep stretch, making it an ideal setting for those seeking speed and efficiency. Participants are encouraged to push their limits as they aim to complete at least 32 miles (the Ultra distance) in order to earn medals. The true prize, however, goes to the last person standing who will be crowned with a prestigious winner’s trophy.
Supportive amenities such as refreshments and hot food become available after the fifth loop, ensuring that runners remain fueled throughout their endurance journey. Race regulations are designed to maintain fairness: participants must start each hour on the hour from a designated starting corral without delay; staying on course is mandatory except for brief restroom breaks; and slower runners must yield to faster ones during overtaking.
The race commences on Friday evening, with specific timing details communicated via email three days prior. This unconventional format tests not only physical endurance but also mental fortitude as competitors push through the night towards an open-ended finish line. Will you be the one who endures until the very last loop?
Prepare for a thrilling and unforgettable experience where every mile brings new challenges and opportunities to demonstrate your grit, determination, and passion for running.
