No. Looking at such competitors from ethnic or racial perspectives is dogmatic racism. 99% of Kenyans are not superior at running marathons and 99% of African Americans do not excel at basketball or football more than others. It is dogmatic racism (by you) to fixate on the 1% reasoning, ignoring the decisive other 99%.
For example, you could have stated that tall people excel at basketball and that people from regions of high altitudes and hot climates where walking long distances has been a social requirement for countless generations excel at track events. But YOU picked RACE/ethnicity and claimed THAT was your basis for what you call logic, when I call it based in dogmatic racism.
You are making your case for racism that is a fairly old one at the academic level - calling it being pragmatic.
