I'm pretty sure that even if someone paid you to attempt what artist and daredevil Eskil did in the appropriately named for this stunt Trollstigen (Trolls' Path in English), a winding mountain road in his home country of Norway, if not all, most of you would answer, "thank you very much but there's no way in hell I'm doing this".
The Norwegian rode his bicycle backwards down the 4.5 kilometers (2.8 miles) long road down the hill (with a 10% slope), at some point reaching an alleged speed of 80km/h or 50mph (something we can’t confirm).
And if that's not crazy enough, how about the fact that the road wasn't closed as we see him trying to avoid traffic?
Here's what he says about himself on his dedicated website:
"Eskil has spent his entire life living on the edge creating art that makes a difference. The goal is not just to leave an imprint on mind. The goal is to move boundaries, inspire and show humans all over the world that anything is possible."
"Eskil performs live, at TV-programs, in movies and exceptionally by promotional actions. He is also giving lectures about his journey from a little village in Norway to great international success, his unique working methods and the balance between life and death."
