My sister Bea died in November last year at the age of 26, after a three year struggle with cancer. To celebrate her and our mum Pat, who also died of cancer when Bea was a girl, I'm going to swim two miles in the Serpentine in Hyde Park, London on 17th September. I'm raising money for Macmillan, who do brilliant work helping the millions who live with cancer in the UK each year.

Encouragement and advice also welcome if you don't have cash to spare!
