In 2026, you can run one of the world’s most iconic marathons! As you weave from east to west, you’ll discover London’s stunning landmarks and sights, such as Tower Bridge, Canary Wharf, the London Eye and Big Ben, with an epic finish line on The Mall.

When you run the London Marathon for One25, you’ll make every mile matter. You’re raising vital funds to support women who are street sex-working — many experiencing homelessness, violence, addiction, and trauma. You’re helping them feel seen, supported, and strong enough to rewrite their story. You’ll be doing something extraordinary
