Take on Challenge London for GOSH
"I found the triathlon physically hard but so rewarding. I feel so proud to have finished it and I loved training for it; it gets you so fit.
I would say to anyone thinking of doing it for Great Ormond Street Hospital Children’s Charity, do it! I am 54 this year and doing my second triathlon, and when you think about the children at GOSH, it is nothing compared to what they go through. So go for it!"
