An incredible new video featuring Scottish cyclist Danny MacAskill has been viewed millions of times online. The short film shows Danny returning to his native Isle of Skye to cross the Black Cuillin ridge line. This is not a film for the weak of heart, or for those suffering from severe vertigo. The scenery may be stunning, but traversing the ridge on a bicycle looks, frankly, terrifying.
So, watch below in amazement if you dare. And if you'd like to find out more about the making of this film you can read about it here or, for those in the UK, view a short BBC documentary here.
