40 minutes in Green

I ran today for the first time 40 minutes in green zone.    It was hard to run slow.    However the run was very comfortable today even under this high temperature.   Theory says that training should be done between 65-85% of maximum heart rate, MHR, therefore I should be running most of the time in my green zone.

Nike+ 6.65k, time 50:06, pace 7:31, A/MHR = 151/162
