Marathon Training

I experienced the first hitch in my training schedule, I skipped my workout yesterday (too tired after a long day at work), but made it up tonight:

Tempo run 7 miles total

2-mile warm up

4 miles at an 8:59 pace

My actual splits were:
1 in 9:01
1 in 8:38
1 in 8:48
1 in 8:21

1 mile cool down.

To be honest, the cool down was a mix of walking and jogging, actually running the cool down is getting harder and harder after my tempo runs, but I figure its still part of my mileage so I gotta work that out.
