    A more realistic formula (by my experience) is 220 - 65% times your age. Forgot where I read it but I found it on a Google search.

    Max heart rate

    ^ yeah I like that one better .. But I've also been higher for a sustained periods and felt ok. I more or less don't want to go over 185..
    PO is a liberal echo chamber.

    Talked to my doc during my last physical while he was checking my EKG. I'm about to be 47 and have seen a max heart rate of 196 on 3 different monitors and have averaged 169 for 6-7 hours during several mountain bike races.

    This really concerned me at first but the doc and a heart specialist were not at all concerned after looking at my chart and we're actually quite impressed. Everyone's is different and mine can run higher than most. Am I cooked after those efforts? Absolutely. You need to find yours on your own and then figure out where you're comfortable. I know that I'm conversation comfortable up to 165.

    I guess this doesn't really help with the calculations for a general baseline to be established.

    Nailed it. Max heart rate is genetic, and does not change with age. As we age, we may find it more difficult to reach that rate, but your anaerobic threshold will only drift with training.

    Maximum heart rate is individual. The 220 minus your age and as others have said it an "average" guide or representation. But it is as accurate as saying all of us have a body temperature of 98.6. As we all know average body temperature varies a great deal among adults.

    It's true that as you age your maximum attainable heart rate will decrease. That decrease is an absolute certainty but what's not certain is the what that rate of decrease is. (You don't go down one beat per year for instance. It tends to decline in certain periods of time as you age.)

    The only way to know your Max HR is to electronically measure it when you are maxed out several times on a climb that you gradually work into and are fully warmed up. Then just use that as your individual max HR for figuring out whatever it is you want to do regarding training or pace, etc.

    Actually for workouts up to a point you can learn to "feel" where you are in regards your zone per that "pounding" heart and the rate of breathing.

    165 is likely not your max. Climb hard for a duration, than go all out till you're cross-eyed, nearly pass out and fall off the bike. That'll be close to your max. You can maintain max HR only for a very short time, usually less than a minute.
    ... 'cuz that's how I roll.

    I think I will skip the sudden death method and go with what I have. I am to old for all that.

    So is "resting HR" your rate asleep in bed or sitting on the couch or (say) after you are all kitted up for a ride?
