James Kingston, a British free runner who describes himself as a 'professional adventurer' has scaled to the top of a bridge in Ukraine - and performed a backflip whilst 380 feet in the air.
Along with friend Mustang Wanted, James climbs unaided to the top of the Moscow Bridge in Kiev, before doing a backflip at the top.
Perhaps one of the most stomach-churning moments of the clip is when Mustang Wanted hangs over the edge - with the only thing stopping him from falling to his death being his friend's hand.
After the stunt, the pair are questioned by Ukraine police, who ask them why they were doing somersaults. Mustang replies 'Because he is the English Spider-Man.'
