When your HRM and percieved effort dont agree?
What method did you use to determine what your zones are? Not all methods are accurate for all people so it's possible you are working with the wrong set of numbers and that 85% is really 80% or less.
Keep in mind that many factors contribute to HR abnormalities-
weather (hot days especially), caffeine, hydration status, body position (swim vs. bike vs. run) etc. So it is always good to refer to perceived effort when these factors are in question. When the HR monitor and your effort don't match, maybe think about these factors and document them in a log for later comparison.
"Do just once what others say you can't do, and you will never pay attention to their limitations again."
if you're new to using a HRM, it probably means you need to slow down. using a HRM changes your perspective on what a 70% effort really is. and don't worry, you will speed back up as your body gets more efficient.
as PJT suggested above, while the generic age formula works for most of the population, it does not always work for everyone. a VO2 max test would determine that for sure ($$).

I was just following my forrunner output. I am guessing that they calculate it on the age formual unless it reads a HR higher then that correct?
most likely they do, but i'm not directly familiar with the garmin products...someone else here might know; there are a bunch of garmin owners on this forum
setting a PR during base training would be having the lowest HR ever for a particular course with a fast time. if your HR is high, it means you're working harder for that PR. you want to work LESS (ie more efficient) for that PR during base
when i first got a HRM, i had a similar experience of feeling like my HR was higher than what I imagined it to be based on RPE. i discovered i was incapable of actually running at a zone 1 pace...i was out of shape and for me zone 1 was walking. actually zone 2 & 3 were walking too, because my HR would just shoot up when i started to jog. but, after a month or so, my heart started to adjust and i was able to train in designated zones. for someone more advanced, all it means is that it forces you to go slower in order to get the benefits of lower zone training. as your body gets more efficient, your speed will increase while your HR will stay the same
In the first few months with a HRM, you should just wear it and see the readings and compare to your efforts. figure out what speed you run in each zone based on the HR readings
i actually got my VO2 tested and established my HR training zones and they matched the generic age formulas within a beat or two. as a result of that, I suspect the formulas are largely accurate for most folks...

I'm not sure what method the garmin uses to initially set it, but you can actually have it calculate your zones for you based on your HR over time. This does mean it takes a bit for it to figure them out though (I'm not sure how long it took to get a better setting on mine).
Like others have said though you can also just do a test and get better guestimates and enter those in the garmin.


I have only been training with a HRM for about a month now and I am just wondering when your out there running (or whatever) and your HR is off the chart but you still feel good do you keep cruising at a comfortable pace or slow down?
I am currently in a base phase (training for next year) and in my last run which felt great my average HR was about 85%ish. This is borderline in the wrong zone is it not?
Now I set a new PR during this run which might have given me a high apart from the actual run but in this case would you slow up a bit to get the HR down?
