I have little faith in the HR data that I see based on my wrist watch. In races, and when I was in shape,
I could tell simply by feel, with that being backed up by time/splits taken on my watch or from on course clocks.
(based on recent race data)
I also had enough experience in races to know how fast to go out. I think self knowledge of your capabilities
combined with the discipline to not suddenly believe you will discover some unknown new speed, will get you
your best time. Before many of my marathons, I would try to run a half marathon about 7-8 weeks before
and a 10k about 2 weeks before. Then you know what your limits/capabilities are. That's hard data.
(during a racer just a typical run) As long as I was not huffing/puffing breathing hard,
I knew I had room to go at least a little to somewhat harder.
Then it mostly became a guessing game, if you want to call it that, combined with
course knowledge of how difficult/easy the remaining course was likely to be.
That and patience, since even with only a mile or so left in a marathon, you can expend yourself
to close to 100%.
My best marathon (MCM 2002) - I ran a 3:08
First 10 in 71 minutes
Second 10 in 70 minutes
last 10K, which includes the hill around Iwo Jima, only 90 sec slower than the first 10K.
(actually, I don't remember for sure how much slower my last 10k was that day. The last 10k might have been
more like only 45 sec off the first one).
now at age 69, I'm a long way from the combined speed/stamina I had into my late 40s. In 2011, age 54, I ran a 3:25.
A lot of what we call 'thought' is just mental activity
When you are accustomed to privilege, equality feels like oppression
Those who are convinced of absurdities, can be convinced to commit atrocities
