While an 11-second 100-meter can win a high school student the league or district championship, a good state champion runs sub-11, and among 100 state champions only a few have any hope of running near 10 seconds.

As our understanding of complex traits improves, genetic engineers will be able to modify strength, size, explosiveness, endurance, quickness, speed, and even the determination and drive required for extensive athletic training. Estimates of the number of variants controlling height and cognitive ability, two of the most complex traits, yield results in the range of 10,000.

Nevertheless, it is almost certain that viable individuals will exist with higher ability level than any person has ever had.
