today was a better run, but i still feel like i'm working too hard, maybe. it's funny. i was trying to start off slow, 6.0 mph. but then i bumped up, interval training to 6.5 and guess what? it felt better, more of a natural pace. still, i didn't want to overdo it, so i kept it kinda slow. it's kinda fun, working hard, building my endurance, run by run, mile by mile.
