Run 100 Miles in October 2026
Run 100 miles between 1st and 31st October and raise vital funds to support children and young people with cancer.
Experience one of the UK’s most iconic running events! The Royal Parks Half Marathon offers a stunning 13.1-mile route through the heart of London, combining world-famous landmarks with the beauty of four Royal Parks — Hyde Park, The Green Park, St James’s Park, and Kensington Gardens.
This closed-road course takes you past historic sights like Buckingham Palace, the Houses of Parliament, and the Royal Albert Hall, all while immersing you in vibrant autumn scenery. With a mostly flat route and gentle undulations, it’s perfect for runners of all abilities — whether you’re chasing a personal best or taking on your first half marathon.
Join Team Young Lives for this truly unique event to support children and young people with cancer and their families.
We love our runners, and we want them to have an awesome experience at the Royal Parks Half Marathon! Some of the benefits of joining our team are:
When a child is diagnosed with cancer life becomes full of fear, for them and their family. Fear of treatment, but also of families being torn apart, overwhelming money worries, of having nowhere to turn, no one to talk to.
At Young Lives vs Cancer, we help families find the strength to face whatever cancer throws at them. We provide grants and free accommodation close to hospital to help with spiralling costs. Our care teams are on hand to help families with everything from getting benefits to treatment closer to home. And we lobby the government to make sure they get the support they’re entitled to. Powered by the kindness of our supporters, we’ll face it all together.
Join us at the Royal Parks Half Marathon 2026 and use your miles to make a difference to young cancer patients.
