Everyone is different so it's very difficult to compare. I'm 67 and a strong rider for my age group. Resting heart rate in the low to mid 50's. My max is around 155s and on many rides I never go above 150.
To get above 150 I'm usually riding a hill with a grade above 8% where I stay in my large front ring. My average heart rate ytd after 2,500 miles is in low 120's. Frankly I pay much more attention to how hard I'm breathing then my heart rate.
