DMZ, I would say one never normally reaches one's HRmax in a race. Although one's heart rate will often climb throughout a race, tiredness towards the end prevents one from reaching HRmax. You're more likely to get close to it in artificial circumstances, such as being thoroughly warmed up by a decent amount of easy running, then doing three longish hill surges, with your HR at the end of the 3rd being a decent indicator.
I've gone on the basis of the highest HR I've seen after a finishing sprint at a parkrun and added 4 beats to that. I think that's reasonably close.

I think if you can manage a sprint (a significant increase in speed) at the end of a race, then there's a good chance of hitting your max. When I used to race with HR strap. I saw 207 at the end of a three mile race, 206 in XC, and various other numbers above 200.

Actually, just revisiting my training records, in my last three races (10k or 5k) I maxed out at 184 bpm each time. Interval sessions, hill training, I never get over 179/180, sometimes only 178 - only about 93% of my max, if the max is right. I think I'm just not pushing myself as much as I could in training - not fit enough? But even then I think it's odd that there's only one race route where I get up to 191.

Thanks for your responses J2R and SPR. I certainly get my highest HR readings in races! Maybe I'll try an artificial test of the type you suggest J2R.

I have no interest in hitting my max in training, absolutely no reason to...

DMZ - Your situation isn't that odd. As you said, there was a hill at the end, pushing yourself at the end of a race uphill is likely to lead to HRs close to (if not at) max.

SPR I thought (from Daniels, Pfitzinger etc) that you only get the benefit of VO2max sessions if you're up at 94-98% HRmax during the intervals?

DMZ, based on evidence of me, and similar circumstances, I would say your 191 is likely to be at or very close to your max hr. Not getting that close in any kind of "normal" circumstances is completely to be expected. Could you find a parkrun with an uphill finish to try?
Currently, I can't get anywhere near what I expect my mhr to be (though it's not been tested for a while); my cardio is I think considerably ahead of my legs.

FWIW, I don't think it's that vital to be certain to the exact heart beat what your HRmax is, as long as you're within 2-3 beats either way. It doesn't make any significant difference to your training. That is, if you want to train at 90% of your HRmax, then anything in the 89-91% range is going to have pretty well exactly the same training benefit.
