Looking for a way to explore some of the finest landmarks London has to offer, while taking on a running challenge with a difference? This might be the race for you! From the Bowler hat send off to the Roman reception; amazing samba bands to the London Show Choir, runners and spectators alike will be kept entertained throughout the course.
If you have your own place for the 2026 event, you can still join Team Marsden today and make a difference to the lives of people with cancer around the world.
• Sign up via the registration form. Registration is £30 per person and we ask each participant to reach a minimum fundraising target of £350.
• Once you’ve signed up, you’ll be added to the official event console to claim your charity place with the event organisers.

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 Cancer Charity 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.
