In reply to RocUp Holidays:
I went on the first Rocup holiday in Kalymnos last September and it was the best experience ever. It really helped me to improve my climbing and it gave me a great insight on what I needed to improve on. Leah and Robin where both coaching on the holiday in Kalymnos as well and they are both world class coaches, they are super friendly and very supportive. I would urge anyone interested in improving as a climber and climbing with some fantastic people to go on a Rocup holiday or a pop session I know I'm deferentially going to book on another one.
