My brother-in-law tried it a couple of years back when we were all in Pamporovo together and he had to have two weeks off work when he returned 'cos he was so sore!!!
He's never felt the urge to do it again I'm pleased to say
You just miss us - we're there half term week 17th Feb. Needless to say, i will be sticking to skiing - one of us needs to return to work in one piece!
