10.5 MILE RACE

We are delighted to be hosting the Beast of Bryn 2026 (Bwystfil Y Bryn)

This race was first established by BRAG (Bryn Residents Action Group) in 2011 and quickly grew in size and reputation. It was put on hold for a few years then re-started in 2022 as the Covid-19 restrictions eased. Since 2024, The Beast of Bryn has been brought back into community management, orginised by B.R.A.G. We have two distances to choose from – 6.5 mile or 10 mile. The route passes through the mountains of Afan Argoed, with stunning views throughout.
