Ride 3:00 on, 30sec off x 5 at 350w avg. Took one minute off and dod 7:30 at 300w. Short ride but good intensity. HR was in the upper 150’s to low 160’s. Also rode last Sundays last indoor TT of the winter series. Had the same issue as the last ride in February where my HR went to 170+ about three minutes in and stayed there, hitting 176 over the last few minutes all the while power is slipping into the 280’s. Hve to think that the ComupTrainers are just old and perpetually out of calibration. It is a great HR workout and says that I can sustain a higher HR than I usually hold in most TT’s.
