very easy 3.5 miles

Still in recovery mode from yesterday's hill workout so coach told me to do the 3.5 miles very easy this morning.  Everything felt good for the first 2.5 miles then the legs went dead even at the slow pace.  Times were 17:49 at the turn (10:11 ppm) and 30:42 at he 3 mile mark (10:14 ppm).  l crept the last 1/2 mile in 5:32 (11:04 ppm)  Total time was 36:14 for the 3.5 miles (10:22 ppm).
