Triathletes are an entirely different breed from swimmers, cyclists and runners training specifically for a single sport. They may never perform their best ... simultaneously.

Is it possible to record your best times in all three legs of a triathlon in one race? Experts say no. Training for one leg of a triathlon can undermine another leg, making a peak performance sweep pretty impossible. The training required for a best time in running may compromise the fitness required to score a peak performance in cycling. Body musculature alone is markedly different for a swimmer versus a runner versus a cyclist.

Triathletes may have to settle for imperfection, but the benefits of cross training can offset that ever-elusive all-in-one Triple Crown Triathlon. The inherent diversity of triathlon training can be a lot more fun, prevent injury in the middle-age athlete and lead to swifter recovery in between training sessions. Besides, you get three chances to score a personal best!
