My sister, who is an all-round cool person, is doing a marathon(in installments) for the Royal Marsden. Cancer has been hitting close to home for both of us in recent years, so it's a cause extremely dear to our hearts and one well worth supporting. No one should feel in the least bit pressured, but if you do feel like sending a pound or two in Tracy's direction, it would be greatly appreciated.
My sister has had an interesting career trajectory. After many years service in nursing, she retrained to become ... a maths teacher. Not many people do that, and I'm proud of her.
