Well, apparently this is happening:
A standard hockey rink is roughly 200 feet long and 85 feet wide, which means that the perimeter is going to be somewhere in the neighborhood of 570 feet. For our purposes, and because you wouldn't be straddling the boards while skating anyway, let's use 550. Anyhow, let's say that for some reason you wanted to skate a mile on the ice, that'd be just over nine and a half times around the rink. And if - for reasons we can't begin to imagine - you wanted to skate 125 miles? That means you'd have to skate around the rink 1,200 times. Or you could go to the Netherlands.
