Have You Ever Achieved A Runner's High?

Allegedly, if you run far enough and hard enough, you reach this euphoric zone referred to as simply 'runner's high'.

Or, if you're anything like me, suddenly, out of nowhere, you really have to pee SUPER bad and you've jogged yourself a good half-mile away from an accessible toilet.

Have any joggers out there achieved a runner's high? Or have you just achieved leg cramps and sweat in weird places?
