Here we go again. 2024 work underway with a 4x6 done on the trainer in resistance mode.
Worrying about HR isn’t the be all end all to me, since so much impacts it (e.g. I had an espresso about 30 mins prior), but I like to make sure it’s nice and high, and it’s a reminder to keep pushing the cadence. 22.5 mins over 90% max and ~15 mins over 95% max are nice healthy numbers though IMO.
