BBC reporter zip wires between London skyscrapers
The London Landmarks Skyscraper Challenge took place over the weekend, raising more than £800,000 for a range of charities.
The event saw some 850 participants abseiling down or zip wiring from the Leadenhall Building - often known as the Cheesegrater - to the Gherkin, high above the streets of the Square Mile.
BBC London's Harry Low decided to give it a go.
