Mile Splits, 9:55.2 (133), 10:00.2 (138)
A little slower than it should have been but kept the HR under control.

Spinning Class

Did a couple of quick miles with a co-worker and then a slow lap to reduce my heart rate back to 140, ran 4 miles for a "Maximum Aerobic Function" Test. 141 is my target heart rate based on the 180 formula.

Maximum Aerobic Function Test

Mile 1            10:09.6        142
Mile 2            10:26.3        142
Mile 3            10:41.4        143
Mile 4            10:57.9        143

Actual distance is about 1.027 miles.  Ran in Lane 2 of the track.

A nice tempo run due to short amount of time. Both mile splits were 9:18 (150, 160 average Heart Rate).

Estimated Distance. Spinning Class. Recover from long run yesterday.

Was running mile splits of about 9:05 to 9:20, screwed up my HRM and lost them before I could record them though.

Tempo Run. Trying to figure out why I'm a minute per mile slower than I was about 3-4 months ago.
