Join Team Marsden and tackle the UK’s greenest half marathon, running a closed-road route through four of London’s world-famous Royal Parks, and make a difference to cancer patients everywhere.
Please note, the 2025 Royal Parks Half Marathon event is sold out, so the details below are regarding the 2026 event! Make sure to register your interest and we will be in touch as soon as you can sign up to be part of Team Marsden in 2026.
Looking for a new challenge, or preparing to tackle your first half marathon? This closed road route through London's stunning Royal Parks could be the event for you. Be part of something special and enjoy the fast and flat route, before celebrating your achievement at the amazing Food and Fitness Festival with your friends, family and fellow Team Marsden runners.
If you have your own place for the 2025 event, you can still join Team Marsden today and make a difference to the lives of people with cancer around the world.
• Registration is £30 per person and we ask each participant to reach a minimum fundraising target of £350. Register your interest for the 2026 event, and we'll be in touch as soon as our places are available.
• Once you’ve signed up, you’ll be added to the official event console to claim your charity place with the event organisers. You will be sent a separate link via email and will need to complete this to secure your place. After you’ve completed both steps, you’ll be all set to lace up your trainers and get running.
• Once you’ve signed up, you’ll receive one to one support from a dedicated member of the charity team to help you with your fundraising efforts and to answer any questions you may have as you prepare for the big day.
• You’ll also have access to our professional half marathon training plans to encourage you to start logging those miles. Whether it’s your first big race or you’re a seasoned runner, our plans will help structure your training to make sure you are ready for the challenge.
• When you register, you will also be able to join our Team Marsden Runners Facebook group. Our fun, friendly and supportive online community will be there to support you all the way, share top tips and advice and keep you motivated in the run up to the event.

Grant took part in The Royal Parks Half Marathon with his daughter Orla as a way to give back to The Royal Marsden after his treatment 10 years ago.
"Having been treated at the Marsden over 10 years ago, I have run regularly to raise money for the hospital, so it can continue its amazing work. The Royal Parks is my favourite event, really relaxed with such a supportive crowd, as well as super friendly runners. Doesn't matter if you want to set a PB or simply walk most of it - it's a great day and experience. I ran it with my daughter, it was a really happy and emotional day."
Thanks to supporters like Grant and Orla, we continue to be there for everyone who needs us.
