What is the fastest 100m ran by a caucasion person?

Yes but show me the studies that show link between physiological advantages of running with the human genone.

All of the sports you listed are of small niches with little involvement worldwide, while athletics ranks as one of the most participated in sports worldwide, requires almost no expensive facilities, minimal coaching (Bolt going sub 20 as a young teen), minimal strategy, etc

Your digging a big hole Sir :slight_smile:

Any Olympic & WC sprint champions come directly from West Africa nations?
