I’m a 42 y/o Cat 1 MTB’er who also rides road and races crits. Our mtb season ended a month ago and I took 2 weeks off the bike. I’ve only started riding with groups again on the road at a chill to brisk pace. Weather has turned cold so I set up the trainer and climbed on today to ride 60 minutes at endurance pace.
Question is, why was my heart rate higher? Last winter I was riding the endurance pace at 180-190w and heart rate was in zone 2, at 133-138 bpm. Today HR was anywhere from 145-150, (zone 3= bad). What should I adjust, or will my HR settle as I continue to ride the trainer?
I believe my max heart rate to be around 185 and last FTP test in June was 260. Thanks for the help!
