Ahh... Today's gym session went better than yesterday's. I had a better (but still not great :( ) night's sleep and two days of eating healthy and balanced meals at the correct times under my belt. Following Hal Higdon's plan I had to do a 3 mile run at an easy pace. I set the treadmill to do a hill session at no more than level 3 to mimic running outdoors and used my Garmin to keep my heart rate under Zone 4. (I've just realized this is probably closer to 80% instead of Higdon's recommended 65%-75% so I need to set a custom max for my next run.) I did the same yesterday and finished the 3 miles in 30:22 with an average heart rate of 161. Today I did it in 28:35 with an average heart rate of 161 as well.
I really love being able to do this.
