I’m running the London Marathon Championship Race dressed as Captain Underpants (poor judgement — but once you see the costume, I promise you’ll agree I’ve fully committed to the bit) in support of Evelina London Children’s Charity.

I chose Evelina because it supports the hospital where I receive regular cardiac treatment, so I see first-hand the work they do for children — and how much they rely on charitable funding. It’s a genuinely good cause, helping provide better care, equipment and support for young patients and their families.

Thank you for any support — and sincere apologies in advance to anyone who has to witness this live in action on race day.
