Royal Parks Half Marathon 2021 On Sunday, 10 October the Royal Parks Half Marathon will see off the challenge event season in style. Now arguably the most popular London half marathon, the course runs through London's most beautiful parks and the capital's iconic landmarks. This is an amazing running experience with an electric atmosphere, made even more special by running with a worthy cause in mind. We invite you to run for Breast Cancer Haven, with every step powered by the knowledge that you are supporting somebody affected by breast cancer. We have a small number of guaranteed entries and kindly ask that runners raise a minimum of £500. You can register your interest below. Applications close on Friday, 6 August 2021. We also invite anyone who already has a place in the October Royal Parks Half Marathon to fundraise for Breast Cancer Haven with their place. Please contact Ellie Morley via the details below if you are interested. Apply here How we support you: A Breast Cancer Haven running vest to help you stand out from the crowd.
