Breakthrough T1D is proud to once again have charity places in the hugely popular Royal Parks Half Marathon for 2025, and we want YOU to join us.

A half marathon like no other, this 13.1 mile route takes you on closed roads through central London and through four of London's famous Royal Parks - Hyde Park, St James' Park, Green Park and Kensington Gardens.

After you have completed this picturesque run and collected your well-deserved medal, you will be able to enjoy the fabulous food and fitness festival in Hyde Park. With music, entertainment and delicious food, it's the perfect way to bask in the glory of your achievement with your family and supporters.

But, don't just take our word for it - sign up today to experience the Royal Parks Half Marathon for yourself and make some memories to last a lifetime.
