Remember when you were a kid and you yelped in pain as you stepped on a Lego piece on the floor? Now, imagine running on a treadmill covered in Legos. The guys of WheresMyChallenge [1] decided to try out the Lego Treadmill Challenge, and we could almost feel their pain through the screen while watching. The first guy who attempted it couldn't last longer than about 30 seconds and even ended up with some bloody feet after his next go.

We'll pass and do the Jogging Man Challenge [2] instead. Check out the video above for yourself.
