In any case... I'm a bit sore too after my run yesterday. I can definitely feel the lactic acid build up in my quads. -Which is why I wanted to get out for a bit earlier today, just to walk/work it out. I'm hoping to get a run in tomorrow, but the scheduling could be tricky. We'll see.
*However, I did pick up a new pair of earphones. And after Google-ing for a while, I found the proper way that they're meant to "twist to fit". Very cool.
