What you are about to see is Kelly McGarry's silver medal run at the 2013 Red Bull Rampage — an invitation-only competition for freeride mountain bikers.
Here he is starting things off at what we can only assume is the tippy-top of a steep mountain.
As you can see, the path is super narrow.
And the sides of the mountain are used as ramps because HE IS FUCKING CRAZY!
