Looks like the tricky part would be convincing your feet/legs to run at 8+MPH while your head is going significantly less than that.

Anyway, cool and congrats to him!

Ok had to upvote for the title.

Awesome... now make a bigger one

Can someone animate this to make coins shoot out of him every time he falls down?

So it starts by saying he needs to go at 8.65mph, then he runs in a straight line at 17mph.

So what's the reason for all the failures straight after that? Is it nerves, lack of grip on the loop, huge loss of speed running up the steep edge?

I think the issue is maintaining acceleration. He needs to be continuously increasing his speed, which I'm guessing is easier said than done when you're upside down.

Objects in motion yadda yadda. His 18mph is going the wrong direction once he starts up the ramp. And it requires a lot of strength to force his body mass to alter direction through a 360° turn. A car is long and compresses on a wheel. A human body is tall and compresses on the mechanism moving it forward, negating it's own ability to move "forward".

Wouldn't it actually be easier if he maintained exactly 8.65mph (ideally) in the run-up? If he's going any faster, then he'd just be fighting his own linear momentum as soon as the incline started, being that he's not a rolling wheel or ball and instead relies on stationary foot placement and pushing to move. On the other hand, once the direction starts changing you'd have to pump really hard to maintain speed.

I would also imagine he needs to engage his core muscles to keep from folding forward; my understanding is that there would be a significant "outward" force generated, which in this case keeps him on the track, but does so by pushing him against it.

2:29-2:30 for the cool part, video is 2:57 too long.
