Take on London T100 for GOSH Charity
"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!"
John, previous London Triathlon participant.
