Ode to the Sweat Line

Oh, sweat line, how do I love thee, let me count the ways:
1 - It feels cool to exercise hard enough to earn it
2 - ...
3 - ...

I made it 5K tonight!!  In 31:12, slightly less than an average of 6mph.  That almost makes me feel comfortable enough to start planning a work 5K.  Yesterday, I made 1.5, going from 6 - 7 and back down.
