Think you’ve got what it takes to tackle this epic tower-running challenge? Join the 11,000 runners to race to the top of Tower 42, London’s 5th tallest building. In aid of raising money for homelessness charity Shelter, put on your best running shoes and scale the impressive 932 steps, and 42 floors. Runners can either sign up as a solo runner or make it a team effort and race each other to the top. All runners will be kitted out with a technical running top and goodie bag. Sign up here.
