I have been riding for a while but not very regularly.
Usually some morning rides (road bike, flat terrain) in the 16 to 24 miles range at about 16 to 21mph. two or three times a week.
I just purchased my first heart rate monitor and I have been reading a lot on the subject but my values have me very confused.
My resting heart rate is about 60 but my maximum heart rate is at 210 (measured, all out on trainer).
According to my age, (42) I should be in the 177 to 180 range.
At first I was really happy about it.
Then I noticed that when I ride at my usual pace,
my HR stays at about 185-190 when riding at about 20 mph.
Actually it never goes below 175 while riding, even at slow pace.
It's like the lower zones didn't even exist for me.
As soon as the wheels start moving I am shooting up to 80-90%.
Is this because I am out of shape?
My heart is acting like a small engine,
at much higher rpm to deliver the same power.
60 - 70% 126 - 147bpm Fat burning (this is my heart rate when coasting)
70 - 80% 147 - 168bpm Aerobic Improvement (I can barely stay there, I always shoot over 170)
My concern is: at what range should I train for fat burning and aerobic?
Could my high max heart rate be a symptom more than a blessing?
I hope this thread is useful for others as well.
