How to take part
Registration
Registration is £25 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. 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!
Training and fundraising support
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.
The Royal Parks Half Marathon route
Starting in the beautiful Hyde Park, this 13.1 mile closed road route threads it’s way through three more Royal Parks – Green Park, St James’ Park and Kensington Gardens – before returning to Hyde Park, and the amazing atmosphere of the Food and Fitness festival village. There are plenty of iconic landmarks to keep an eye out for on the way, including Buckingham Palace, the Houses of Parliament and Royal Albert Hall. The route is generally flat, making it the perfect opportunity to bag a PB!

A way to say thank you
Klodjana, 42, took part in The Royal Parks Half Marathon as a way to say thank you to The Royal Marsden for the care she received when she was diagnosed with cervical cancer in 2020.
“I’ve raised money for charities before but when you fundraise for somewhere that you think of as home - it enhances the experience so much. I’ve spent so much time at The Royal Marsden, a place which saved my life, so it was really exciting and emotional taking part in this event to support The Royal Marsden Cancer Charity. It was such a positive experience. It felt like it was my own race, and I was running it for myself – it was very personal.”
Thanks to our supporters we continue to be there for everyone who needs us. We ensure the nurses, doctors and research teams at The Royal Marsden can provide the very best care and develop life-saving treatments, which are used across the UK and around the world.
