Royal Parks Half Marathon 2025

Run in this stunning half marathon and raise funds for Greenhouse Sports

Join 16,000 runners on Sunday 12 October for one of the UK’s most iconic races – the Royal Parks Half Marathon. 

This isn’t just a scenic 13.1 miles through Hyde Park, Kensington Gardens, Green Park and St James’s Park. It’s your chance to help rewrite the future for young people growing up in poverty. 

Every mile you run. Every pound you raise. It all adds up to life-changing support for a young person who’s being failed by the system – and lifted by a Greenhouse coach. 

Poverty steals opportunities. You can give it back. 

Run with Team Greenhouse and you’ll get: 

• A Greenhouse Sports running vest – wear it with pride 

• Expert training advice to get you race-ready 

• One-to-one fundraising support 

• Post-race refreshments and a place to rest in Hyde Park 

We’ll be with you every step of the way – cheering you on from sign-up to the finish line.

Ballot place and still want to fundraise?

If you’ve already secured your spot through the public ballot, you can still run for Greenhouse Sports. There’s no minimum fundraising target – just raise what you can. We’ll back you all the way.

I found the event to be challenging but extremely enjoyable. The incredible support from the Greenhouse Sports team and the whole crowd was fantastic and made a real difference. The course itself must be one of the best in the world to run, so it was great running it for that reason, but also knowing that the money raised is going to such a fantastic charity and such an important cause. I would definitely recommend it to anyone.
