A British freerunning and parkour champion has been showing off his spectacular skills in Kazakhstan.
Liverpudlian Ryan Doyle, 32, visited the huge country's capital city Astana as part of his global mission to promote the sport.
He met up with local extreme sports enthusiasts and made a promotional video for local firm Astana Energy.
Doyle, a two times winner of the Red Bull Art of Motion international competition, staged sessions at locations across the city.
Astana Energy wanted to use him as the company felt he summed up the energy of Astana which has been transformed into a modern metropolis in recent years.
And the company's video, in which he shows off some spectacular moves as he runs and jumps between the city's buildings and structures, is making a big impact online.
Netizen ‘ShinShillaShow’ said: "Great footage, wonderful montage of the video. LOVE IT.", while ‘Zhan Kazakh’ added: "Sport means power."
But ‘dmitriy’ pointed out: "There is not much room for jumping here. There are huge distances between the buildings, they are really spread out, it is hard to do parkour."
And ‘Jake’ asked: "Does this project mean that anyone can jump from one floor to another in their tracksuits and nobody will punish you?"
Doyle is a freerunner, martial artist, coach and actor, and a founding athlete of the World Freerunning and Parkour Federation.
He became the first international freerunning champion, winning the Red Bull - Art of Motion in Vienna 2007, then reclaiming the title in Sao Paulo, Brazil, in 2011.
Kazakhstan is the world's largest landlocked country and the ninth largest overall. It hast vast mineral reserves and is the economic powerhouse of Central Asia.
