Jo joined Team Marsden in 2024, as a way to say thank you for the care she receives on the charity funded TRAK-ER clinical trial at The Royal Marsden.
'For me, being involved with the hospital as a patient first-hand, really inspired me to want to get involved and give something back. Marathon day was surreal, it felt like a big party! The streets were lined thick from the beginning to the end with supporters cheering on all the runners. It is by far my most favourite marathon. I would definitely recommend taking on the London Marathon, I absolutely loved it and would do it again in a heartbeat!'
Thanks to people like Jo, we can continue to be there for people who need us.
We’d love to keep you up to date with inspiring stories, the latest breakthroughs, and ways you can make a difference.
