Run for Charity
With general entries sold out, why not run for charity and be there on the day? Charity is at the heart of the Brecon Carreg CDF 10K – where many will be raising money for fantastic good causes. Knowing your run has helped others gives a huge boost to the satisfaction you’ll feel on finishing the race – and keep you motivated during your training.
We encourage you to fundraise for our Lead Charity Kidney Wales, but it’s up to you!
