Unicycling is widely regarded as being as hard as it looks. With that in mind now imagine unicycling down the side of a mountain.
Well GoPro has managed to find some 'offroad' unicyclers who decided to do just that, shunning the second wheel for what looks like one of the most dangerous mountain descents we've seen.
Honestly just jumping off the top of that mountain looks safer than this, in fact it probably is.
That didn't stop John LeSage and 18 others from throwing themselves into the hands of fate as they hopped and balanced their way from outcrop to outcrop.
Of course GoPros were on hand to capture this lunacy so that we can look on in awe from the safety of our own homes.
