I'm 53 and my real Max HR is 192 bpm not formula.
My weekly weekend rides average 3hrs or slightly less and 38-44 miles my HR averages around 157 bpm and I just about always see 184 - 188 bpm on every ride at some point. Climbing is any where from 2400 to 3900 on these rides also, not just flat rides.
