Tianmen Mountain in China has the ultimate parkour course, and it's not for the faint of heart.
Brave YouTuber Calen Chan took on what he claims is the "World's Largest Parkour Course" with a GoPro camera in his mouth to capture the run that he says spanned about three football fields long.
Along the way, Chan dodged tourists who were just hanging out on the course and nailed jumps he estimated to between five and 10 feet high.
"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!" Chan wrote in the video's description.
