I would be keen to hear peoples thoughts on how heart rate changes from a morning workout to lunchtime or afternoon workout.
This morning I did Carillon and my heart rate was where it normally is for morning workouts.
Yesterday I did bald knob an easy workout and my heart rate was the same but the ride was recovery and power output well less.
I have noted that any session I do later in the day seems to be the same, with a higher heart rate. Is this a normal difference with people?
