However, I'm a little puzzled or surprised by the low numbers you claim for HR max and recovery times. Have you talked to a real heart doctor? I know that at our age we are supposed to have lower HR max and other things, but I've never known anyone that regularly gets cardio, even when taking off a year or so have the numbers you mention. But I"m not quite your age so maybe that's to happen yet.

If a full cardio workout is within your health abilities, I'd think limiting your HR and never going above a bad thing. For certain you may not need or want to spend a lot of time at the anaerobic levels I or others might do, because it's not necessarily making us better performing, it just fills an addiction. However you should be able to put out a good effort on climbs and sometimes flats for a sprint then see you HR come back to some level that you allows you to finish with comfortable energy reserves what ever distance you are cycling that day.

Shorter trips, I usually have a higher average HR. Longer trips usually have a lower average HR. But I still end longer trips with the same speeds as shorter ones. Just that I can't maintain those speeds for as long a time.

Also, do you replenish most of the carbs you burn on rides? If not, there's a problem to think about if these rides you are talking about are a couple hours or more in time.
