The world's largest parkour course
This footage comes from Calen Chan, who took on the world's largest parkour course called Skyladder in Tianman Mountain, China. The course is a sprawling, 999 step long run all at a 45-degree angle. From top to bottom, the distance is equal to3 football pitches! The most impressive part? Chan filmed it all with a GoPro in his mouth:
'I had the wonderful opportunity to come and play here at this beautiful location called Heaven’s Gate', Chan says of the course. Obviously this was difficult, and I physically couldn’t sprint down the entire path of deadly drops without slowing down, but I did my best!'
Don't worry Calen, it's not like we could have done any better!
