Running to give thanks
Grace-Anna took part in The London Landmarks Half Marathon as a way to give back to The Royal Marsden for providing care for her mum and brother.
“I wanted to run for The Royal Marsden as my mum went through breast cancer treatment a few years ago, and my brother received leukaemia treatment at the hospital. Both are now both thankfully in remission, but I wanted to do something to give back. When I started running, the cheers from the crowds, the well wishes from spectators, and the music were so inspirational - it made all those months of training worth it. I especially loved the Royal Marsden cheer station - it helped give me that final push and reminded me of what this was all for.
Thanks to our supporters we continue to be there for everyone who needs us. We ensure the nurses, doctors and researchers at The Royal Marsden can provide the very best care and develop life-saving treatments.
