Where did you hurt after running?
I'm not a runner, but I walked a 5k yesterday (E is 8 weeks old), which was the most I've walked at once in many months. I jogged a bit here and there, and today I'm sore! The weirdest part is that I felt pain/pressure in the crotchal region, like when I was pregnant. WTH? It used to feel like the kid would fall out when I walked, but there's nothing there now!
