Your response suggested that if you were beating the Kenyans, then focusing on weight might be justified; or, at a minimum, if you weren't beating the Kenyans then weight watching us not justified. So you introduced relativism into the discussion and I wanted to carry that out to its logical end.
Not sure why there was a need to imply I am being myopic. Not very SJW of you to throw out ad hominem attacks.
Let's follow your next bit of reasoning out to its logical conclusion. If the point of running is not to win, but to do your best (I will ignore the "for that day" concept - it is disingenuous and inherently inconsistent with Our sport), why wouldn't you watch your weight (in a healthy way) if it will improve performance and help you each true personal running enlightenment?
I'm not suggesting that there is a shared magical number for everyone, or even that each person's number stays consistent over time. I ran my PRs at 140, but now race at 145. Were I to race at 150-155, I'd be slower and dissatisfied. Why wouldn't I eat a healthy balanced diet, with an eye toward calorie consumption to increase my satisfaction?
Maybe your number is 170, but the "Weight watching is inherently wrong" mantra is wrong headed because it simply imposed your values on others.
To each their own, homey.
