3.75 miles on the treadmill today, plus some additional walking.

Is it normal to feel kinda crappy for the first 30 minutes, then something clicks and you feel on top of the world? Is that the fabled "runner's high"? If so, I'm feeling it! It's almost like clockwork. It feels SO hard at first, then gets better and better.

Come to think of it, I often have the same experience on a ride....
