Thanks cymru
I was around with Josh at the start of the walk, but lost him a little while into it when I was trying to find the other people I should have been with.
Thanks to everyone who sponsored me, I did finish it - I'll scan my finishing certificate up later in the week - it took me about 2 and a half hours, and even though I was OK at the end, I was very glad I didn't have to go out to see a client the following day
