How do triathletes manage to not completely suck at all three disciplines, and whats the secret to their magical ability to not be utterly mediocre in at least two of them? Is it just a matter of spreading their incompetence evenly across swim, bike, and run, or is there some actual science behind how theyre able to excel in one area and not completely embarrass themselves in the others? And whats the deal with how their performance in one discipline somehow magically enhances their abilities in the others - is it just a case of the placebo effect, or is there some actual physiological benefit to being a jack-of-all-trades, master-of-none?
