I Love My Heart Rate Monitor

I went back to the Ridgeland mountain bike trails again today, Sunday.  This time I had my heart rate monitor.  I covered 9 miles minus the distance I walked warming up for about 5 minutes according to the information about the trails.  I ran for 1:42:19.  Assuming the distance of the trails is correct, my pace was around 11:41.  I felt great the whole time, the highest my heart got was 144, briefly.  My heart rate average was 134, which is well within my zone 2 heart rate.  I could tell that my HR never got too high because I could always slow down and get my heart rate down to between 127 and 130, which is the low end of zone 2.  This run was a 4.
