My experience on the 20 Mile (32km) Beast of the Brecons Race organised by https://www.limitlesstrails.co.uk/
Starting and finishing from Gilestone Farm - Talybont in the Brecon Beacon National Park. The route ascends Wuan Rydd (769m) and the surrounding mountains and forests. Two checkpoints to refuel and friendly race organisers and marshals, it was an excellent race.
