Get out there and blast it. When you collapse in a heap (very unlikely) you will know you've exceeded your max.
By worrying about your HR all the time, you are perhaps not getting the full benefit from your training.
"Oh dear, my hearts beating at 177.352 - that's .352 above what my MHR should be - I'd better slow down." 😄 TYSON
Is worrying about MHR the new "worrying about penis size" size? Honestly, how is it any different. Is knowing that your penis is bigger or smaller than average going to change performance. Can we agree on a new saying, like its not the size of the ship or something. I.E., it's not the speed of the rider's heart, but the heart of the speedy rider?
I also think that this issue is so persistent because all of us see flare ups in training that well exceed these medically endorsed formulas and the suggestion is that we will have a heart attack if we don't keep it below the proscribed zone. But what is true for a fat slob undergoing a stess test is probably not true for serious fit cyclists.
I did find the Hr figures published during the TdF pretty interesting, but it certainly wasn't the guy that could keep it pinned at the max that won.
The enduro guy is right, for centuries or long races, a HRM is key to keeping you from blowing up too soon. Over 8 hours, those few beats over or under the zone do matter. But on a two hour training ride? If you have to push it for a few minutes to stay with the pack, you are still better off than hanging back and getting dropped.
