Competitors race individually across a thin cable, 30-mm thick, which is stretched one-km long over the Han River.
The Cable was designed by the UK engineers Tony Gee & Partners.
Of the 18 highwire walkers competing, 16 successfully completed the walk, earning the distinction of co-owning the Guinness World Record for longest skywalk.
One competitor, Jorge Arturo Ojeda, fell halfway through the walk dropping his balance pole.
He was able to regain his footing after being brought a new pole and still completed the walk finishing with the 7th best time.
