Trails & Tarmac 12 hour Back Yard Ultra

About this event

The Trails & Tarmac 12 Hour Back Yard Ultra brings a tactical twist to the classic format. Runners complete a 6.7km loop every hour, on the hour, for as long as they can keep going. The course weaves through the Welsh countryside around Llangattock, mixing trail sections with stretches of tarmac. It's the back yard ultra format in its purest form — not a race against others, but a test of pacing, mental stamina, and knowing when to push versus when to survive. The winner is simply the last person standing. With modest elevation per lap, the challenge comes from the relentless rhythm and cumulative fatigue. This format demands experience with ultra distances and a solid understanding of fueling and rest management between loops.
