Another Slow Go

Today I did 5+ miles at a pretty slow pace on a treadmill at the Y. I did the first mile slowly: ~9:30, then did the next 3.75 miles at a better -more normal pace (about 31 minutes) and actually did a decent cool down. I always have more trouble on the treadmill - maybe the treadmill hills are harder than the real hill, or maybe the winter flu's correlate well with the treadmill work? Hopefully I'll be back out later this week.
