Just did a hour of power Tuesday nighter last night. Training Peaks said I set some 2020 heart rate PR’s which got me comparing to last year. Overall, heart rate this year is down like 10BPM or more while peak power for 5 second, 30 second, 1 minute are all the same as last year. More bizarre my 5 minute and 20-30 minute power is up this year yet heart rate is still down.
Most of you might be thinking this is a good thing but, at 52 I’ve been watching HR slide over the years and 10-15BPM compared to 2019 seems huge. Being able to do the same power but, not have as much “buffer” until I max out the heart rate leads to more blow ups/going in the red sooner it seems.
EKG and other tests were all normal this past April in routine checkups. Anyone have any insight or similar experience?. More intrigued than worried.
edit: same PM, same HR strap.
