I finally was able to reach over 100% bpm during a sprint on the trainer. This means that all my zones will now be a little higher. Also it means the next time I have to shoot for more than 192 to see what is my real max bpm.
Training with HR involves a lot of guessing. The more precise information you try to get out of it, the more this problem becomes apparent. I found that temperature, hydration, and blood glucose levels affected my HR quite a bit. Some days, I could ride at 195 for over an hour but on other days, I couldn't even ride at 185.
So I gave up on HR many years ago.

I do understand that using % of MHR is guessing the other zones. But I have no better way to do it.
I'll probably switch from HR to lap time when summer comes. But for now it's the most accurate objective measurement of effort I have. Just to make sure I keep training harder.
It's a shame that I did'nt know about the Garmin 305 before. It seems like a great idea to be able to race a virtual competitor. This looks like a great way to know if you are training harder than you ever did before this season.
Lap times are great but how do you know when you have in the middle if you are getting a good lap or not? Maybe I'll get used to it and just know that I have to be at "this time" when I reach "that tree" or something like that.
