Trails & Tarmac Backyard Ultra

Trails & Tarmac Summer 12hr Backyard Ultra

The Trails & Tarmac Summer 12hr Backyard Ultra is a structured endurance event taking place in Crickhowell, deep in the Black Mountains. The race follows a standard backyard ultra format for the majority of the duration, utilizing a 4.167 mile loop. The course terrain is a 50/50 split between trail and tarmac surfaces. Most of the route consists of relatively flat terrain, featuring one gradual climb and a short steep section.

Participants must be in the starting corral before the bell sounds. Each new loop begins precisely one hour after the previous start. Runners are disqualified if they do not complete a loop within the one-hour window or if they are not present in the starting corral at the beginning of a lap. Trekking poles and other artificial aids are not permitted on the course.

Distances and formats:

• 4.167 mile loop
• 12 hour event cap
• 32 mile special distinction

The event has a maximum duration of 12 hours. The first eleven laps follow the timed format where completion within the hour is required. The twelfth and final lap is run as a standard race, where the first person to cross the finish line is declared the winner. Medals are awarded to anyone who completes at least one yard, with a special medal designated for those who reach 32 miles.

The site at headquarters includes facilities such as showers, toilets, and medics. Support crews have access to a pop-up kitchen area, while participants are provided with food and water during the event, including hot food after the fifth lap.
