Trails & Tarmac 12hr BackYard Ultra - Summer

The Trails & Tarmac 12hr BackYard Ultra - Summer is a 12-hour race held near Crickhowell in the Black Mountains, in the style of a Backyard Ultra. Each hour, runners depart the corral on the bell for a 4.2-mile loop. They then have the remaining time within that hour to rest, eat, and prepare for the next loop. The format adheres to standard Backyard Ultra principles: begin on time, complete the loop within the hour, continue until unable to proceed, and the final participant still present wins. The course consists of approximately 50% trail and 50% tarmac, featuring one gradual climb, one brief steeper ascent, and ample runnable terrain connecting them. Poles are prohibited, and personal aid is not allowed on the course. Slower participants must yield to faster ones. Any runner completing 32 miles receives an ULTRA medal, and the last individual remaining is awarded the winner's trophy. The race headquarters provides timing, water, snacks, hot food from the fifth loop onwards, space for supporters, and a dedicated preparation area for crews. Supporters must remain outside the corral, and communication with runners is restricted to emergencies.
