Man runs first ever sub-five minute "Beer Mile": Running a mile while chugging a beer in between each lap...
Adam Rifkin stashed this in Beer!
Nowhere near as fun as it sounds. But quite impressive.
This is extremely dangerous. The lifeguards used to have a half marathon for this, but it's a recipe for acute kidney failure and death.
You can see how much pain the guy is in at the end. There's just no good reason to do this.
