Today’s indoor rowing session was another 10K in a sequence of 10Ks being done to explore the correlation of effort level and average heart rate. First, I did a 10K with a heart rate target of 110 BPM from start to finish. HR was virtually a constant 110 BPM from start to finish, but in order to do that, the pace had to start out faster and then slow down from start to finish, to maintain 110 BPM HR. The average pace for that 10K was about 2:26.
Next, a 10K with a target of 2:20/500m average pace, to see what heart rate would do. Pace was maintained at 2:20 from start to finish and HR started out below 110 and finished above 110, to average about 109.9 BPM.
Next, a 10K at an average pace of 2:19/500m. Average HR for that session was about 115 BPM which is about 5 BPM increase for that increase in pace.
Today, 10K at an average of 2:18. Average HR today was quite a bit higher than expected, based on the results of yesterday compared to the day before yesterday. Instead of average HR increasing another 5 BPM, it increased by about 8 BPM, to about 123 BPM.
I haven’t decided what to try tomorrow. But one happy result so far is that there have been no incidents of irregular heartbeat at these very low effort levels. So I might hang out in this region for a while and see what happens with some more tweaking of pace or with the same pace and see if HR slows down at that pace.

Happy rowing to you.
