look at your elevation coninciding with the 219 max. you are telling me that you were at 180 at the top of the hill (where most people would be at their highest), hit your max heart rate at the bottom of the roller (where most people would be at a lower number), and then the number shot down again as you went over top of another roller? i understand that the elevation gain is small, but that is tough to believe.
furthermore, you went from 98 bpm to 210 in around a minute.
it's not like this is a pissing contest. max hr really doesn't mean much when it comes to performance. it is just tough for people to beleive that number, especially considering that it is more likely that your real max is 225-230 based on your ability to hit 219. you either have some weird genetics or you are in need of a better heart rate monitor.
But in this case the elevation gain is less than 10 ft so I think the peaks are actually coinciding with periods of exertion i.e. points at which I am having to drastically having to alter my effort so that I can hang on to the passing group that is going 5mph faster than me.
As far as the 98-210 in one minute. That was during the first lap of a crit. First lap is an all out sprint to jockey for position so I went from standing to going all out in less than a minute. I think that is very possible for my HR to do so. If you'd like to see other examples of this I can show every single crit race i've done where my HR goes from around 100 bpm to my max in the first lap or so.
I truly believe the 219 could be and probably is a freak reading however the original question was "Is it possible for my max HR to change over time?" I think however I've answered it for myself in the fact that my previous MHR was what I thought was my MHR and wasn't a true MHR. I'm assuming I've realized that I can suffer a little more pain and my MHR is probably a little over 200bpm which would make most of the peaks correct and that 219 is probably way off.
