That's Baku, on this occasion. We're actually unaware of any city on the planet of Earth that doesn't bill itself as a "city of contrasts". But whatever. This is about parkour and free-running, and Ryan Doyle is said to be the best in the world at it. Though this Damien Walters dude here isn't too kak either.
So here the 28-year-old Briton is, is in the capital of Azerbaijan (we guessed Kazakhstan, then looked it up and had to change it) doing final-frontier parkour in places of scenic beauty and wonder.
