I know. Exercise and Siân is like Jordan and a burqka. But somehow I have agreed to stumble 26 miles around London (THIS Saturday night) in order to raise money for a breast cancer charity. Sponsoring me would be a real help in getting me over the finishing line at 6am – with or without a bra. Donating through this site is simple, fast and totally secure. It is also the most efficient way to sponsor me: Breakthrough Breast Cancer will receive your money faster and, if you are a UK taxpayer, an extra 28% in tax will be added to your gift at no cost to you. If you do sponsor me, thanks ever so much. Siân xxx
