Almost forgot to mention - I've nominated a charity for the Marathon - Crohns & Colitis UK. Since emailing a few bike industry contacts and all the members of Ystwyth CC, i've raised £320 so far with more promised. http://www.justgiving.com/shelleychilds
I didn't expect this and so thanks very much to all who have sent in some donations.
PS - Dan has apparently raised the stakes in the Sweatband war, coming up with an all-brown number. I'll have to see it to beleive it!
