TM 10 mph, 1% incline, ~160 bpm I went a mile farther than my usual pre-race routine because I felt good and the race is only a 15k ;) I am convinced that the treadmill I used last Saturday was not calibrated correctly because my heart rate was at 185 bpm for the same 10 mph pace. My run today validated my assumption that at my marathon pace my heart rate averages about 160 bpm. Considering my max heart rate is about 195 I think I should be able to run a marathon with an average heart rate of 165-170 (about 85% of max). To get there I will need to start doing more interval training or track work.
