Looking for a challenge? Join us for the Brecon Beacons trail event. Choose between 10K, 24K and 51K ultra distance trail routes. All three routes are quite different to our regular RunThrough courses. They all include some rugged trails, fun climbs, descents and maybe even a stile or two! Whether you are running your first trail race or stepping up to the ultra distance for the first time, we have you covered.

All three routes start in the beautiful  in the village of Talybont-on-Usk, and head out into the hills with stunning views over the Brecon Beacons and surrounding countryside.

The routes will be well flagged and we have plenty of helpers to encourage you on your way to the finish line. Both the 24k and 51K routes will pass by aid stations to allow you to refuel and fill your water bottles.
