Shall I? Shan't I?

Well, obviously, as a finely-tuned athlete I could change my flights tomorrow so that I can hang around here to run the Nike Women's Marathon around San Francisco this weekend. But I suppose I'd best get home.

Registration was taking place in a huge marquee in Union Square this afternoon and there was a great atmosphere. It felt just like the Women's 10k in Glasgow (yes, the sum total of my running career to date) - a wonderful feeling of camaraderie among women of all shapes and sizes. Good luck, girls! (And try not to think about the hills...)
