How to take part
Registration
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. 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.

A way to say thank you
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.
