4 easy followed by 1 hard

Ran 4 easy followed by 1 hard in Cadillac. Less than ideal running conditions with the humidity at 94%. First mile 10:03 and 40:10 (10:03 ppm) at 4 miles. Gave maximum effort to run sub 9:00 for the last mile but ran a 9:00 flat. Total run time was 49:10 (9:50 ppm). This was a tough workout under the weather conditions.
