I was going over my 2015 race data from IMAZ and I have noticed something interesting.
During the second half of my run leg my average HR dropped from 145bpm to 136bpm. My run average run pace over the same period only dropped by 20 seconds per mile. Does it make sense? Could it be attributable to a temperature differential that I did not spot? The run course is 2 loops, so things like the total elevation should be the same. It was raining quite a bit during the first half.
Does it mean that I left a lot on the table? This was my second IM, and I did not run with a HR monitor the first time, so I have nothing to compare this to. I looked at some of the flybys from IMAZ 2015 on Strava and the majority had the HR increasing during the 2nd lap unless they were walking.
Next races on the schedule: none at the moment
