In April I will be running my third World Marathon Major in London, after New York and Berlin.

I am running in aid of the PDSA, who are a great charity that does amazing work. Every pet deserves to lead a happy and healthy life. As the UK's leading veterinary charity, with 51 pet hospitals and more than 380 pet practices, the PDSA improve pets lives through prevention, education and treatment. Every year the PDSA’s dedicated veterinary teams carry out 2.7 million treatments on 470,000 sick and injured pets - all made possible thanks to people like you.
