Trails & Tarmac 12 hour Back Yard Ultra

About this event

The Trails & Tarmac 12 Hour Back Yard Ultra brings the classic elimination format to the Welsh countryside around Llangattock. Runners complete a 6.7-kilometre loop every hour, on the hour, for as long as they can keep going. The course mixes trail sections with stretches of tarmac, with modest elevation per lap — the real challenge comes from the relentless rhythm and cumulative fatigue. It's 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. This format demands experience with ultra distances and a solid understanding of fueling and rest management between loops.
