I went yesterday for the first time, only did the blue owing to being new at this and recovering from over exertion at the gym, but it was great fun. I have a skills training sesh this weekend so am planning on going again next week (advantage of living half an hour away) and tackling the red. If anyone is free during the day (I now get a 2.30 finish one day a week to train for the Dyfi) and fancies it let me know.
