Thanks for all your comments and messages so far. Keep them coming its really keeping me going and in response to some of the questions people have asked:
-Sore but I prefer standing up anyway
-Thurs 24th is the planned finish time
-Matt I'm not answering that cheeky boy
-Only fallen off once so far but I'm not going to admit that
-No nothing special, just normal gaffer tape (£1.99 from B&Q I think)
-Not the toughest thing no, that comes in May when I spend 10 days in Zambia with Susan. Susan I love you!!! (and I hope you've left a Freddy Frog for me in the tuck shop...?)
