Challenge yourself in 2021 and take part in the London Marathon. This world-famous run takes you through the capital’s closed roads around the River Thames. 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. The London Marathon is the largest annual fundraising event in the world!
