6 Miles 44:45 7:27 average.
Used my heart rate monitor but I erased the workout by mistake. Heart rate was higher than last night for running similar pace. I think the treadmill is harder than running outside. I ran hard at the end to see what my heart rate would get up to and the highest it got was 169 similar to last night's run. I kept upping the pace to see if it would go higher but it actually went down once it hit 169. I still think I have not found my highest yet. I will do a hill repeat workout soon to find it.
