The ultimate challenge above London.
The Skyscraper Challenge brought a unique combination of running, abseiling and zip lining to two of London's most iconic skyscrapers — The Cheesegrater and The Gherkin.
Participants ran up 42 floors of The Cheesegrater before choosing their descent: a 200m abseil down the building, or an exhilarating zip wire from The Cheesegrater across to The Gherkin.
It was the first event of its kind in the world, combining two of London's most recognisable landmarks in one extraordinary urban adventure.
