I'm taking part in this event for the second year running, this time in support of Great Ormond St. Hospital. They provide world class care for children, referred from hospitals in the UK and overseas. They touch the lives of thousands of children and families with 220,000 patient visits a year.

I hope to raise £750 for GOSH and to beat last year's time of 5hrs 19mins. I'd really welcome your support for this charity to spur me on.
