We've seen plenty of videos of mountain bikers riding ridiculous downhills, but this one from Marcelo Gutierrez is just crazy.
In the four minute 50 second clip the Colombian rider can be seen riding down 1,000 steps at Monserrate Mountain in Bogotá, the capital city of Colombia.
The death-defying descent was part of the Red Bull Downhill time trial and saw him descend 2,000 metres in just 4 minutes and 27 seconds.
However, it wasn't enough to win, Slovak mountain biker Filip Polc completed the course in a second less … but he didn't have a video camera on him.
