Run #3 What's this—I'm still running?

3.7mi/6km in 45 minutes (4.9mph/8kmph), first stretch (1.3mi/2.1km) in about 11-12 minutes (6.5mph/10.5kmph)
Finally feel like I'm actually running.
The simultaneous sensation of being thirsty and needing to pee is unpleasant.
Also, picked up a credit card around the complex. Will turn in with rent tomorrow, since I can't exactly find this person on facebook. Actually, I just messaged her. She has an interesting family name..
