We’re just going to come right out and say it: you’ll flip over this amazing bike trick.

Cam Zink pulled off an astonishing feat at the Red Bull Rampage when he completed the "biggest freeride mountain bike step-down back flip in history," which went a staggering 78 feet. We get dizzy just watching Zink, so imagine how tough it was for him to actually complete the stunt.

And you thought it was impressive when you took your bike out for a five-mile spin to and from the gym where you pushed the limits by running on the treadmill for 11 minutes instead of 10. Puh-leeze.

Amazingly, Zink only finished in third place. We can only imagine what the guys who finished ahead of him did.
