The three of us are raising funds for Tesco Bank Edinburgh Charity of the Year Place2Be. This is a great charity and we are proud to do our bit.

It would be great if you could donate to this charity and maybe even come along and support us to see three grown men crying whilst hanging from a national landmark (this may be one small step for mankind, but it's a giant (scary) leap for the three of us!)

The book is already open on who will be the biggest quivering wreck at the bottom, with Kevin Coll the early favourite!

Thanks for your support, Dave Tickle, Jon Lake and Kevin Coll.
