Sure. But that was likely induced chemically. So your heart was beating quickly without having to deal with a volume demand at the same time.
Somebody our age zipping up to 200 without a massive external stimulus (drugs, extreme exercise) would be diagnosed with tachycardia. The same aged person topping out at +/- 10% of a predictive age heart rate falls within normal human tolerances. Remember, these limits are based on hundreds of thousands, if not millions, of tests making them statistically valid to the decimal point.
Still, it’s a rough guide. Nothing more.
The gold standard is a fully instrumented stress or VO2 Max test on a treadmill*. It’s an inexpensive test and can be subsequently used to inform an exercise profile. The results it provides are only as good as one’s level of effort though. Quit before you truly reach exhaustion, and that’s where your max HR will be pegged.
Drive yourself to a loss of consciousness, and max heart rate will be set at the point just below where any abnormalities we’re noted. (This almost never happens because the human nervous system is actually pretty good at getting people to cool their jets before passing out.)
For those who have never had one, the test is conducted in parallel with an ECG. So the results show all kinds of things, like oxygen uptake, cardiac rhythm, beats per minute, response to load, heart rate recovery, etc.
I can’t speak to your Strava results (can’t see them as the link doesn’t work without a log-in). I’d say, however, that your tolerance for a high pulse is likely linked more to determination than a safe sustainable limit. You probably have what the Finns would call “sisu” and have driven it hard your whole life, so we’re able to tolerate the massive demand without having a stroke or heart attack.
People can, and do, overdrive themselves. This can be done occasionally by accident but isn’t wise to put into a regular exercise programme… unless you’ve been cleared to do so by a medical specialist. Otherwise, it’s more like Russian roulette and less like surfing with your toes on the nose.
This is why old timers hockey sometimes ends in a funeral.
* Lots of literature showing that treadmill is superior to doing a stress test on an exercise bike, as non-cyclists tend to stop the test early due to muscle fatigue (versus reaching their tolerable cardio limit).

We dreamed of riding waves of air, water, snow, and energy for centuries. When the conditions were right, the things we needed to achieve this came into being. Every idea man has ever had up to that point about time and space were changed. And it keeps on changing whenever we dream. Bio mechanical jazz, man.
