My name is Charlie Yardy, I was born with a large ventricular septal defect (hole in the heart). I had life saving open heart surgery when I was 3 months old and with thanks to the Royal Brompton Hospital I now have a normal working heart. I am challenging myself to a 24hr nonstop ride on Zwift and hopefully I can raise some money for this incredible world-renowned hospital. I will be forever grateful for their expertise and care, I hope that any money raised can go towards helping other sick children. Thank you.
