If Experience Is The Best Teacher, Then The The Best Teacher Is The One With The Most Experience In my career I won the Ironman World Championship in Hawaii six times, I was the champion of the very first Olympic Distance World Championship in Avignon, I was victorious in the Nice International Triathlon all ten times I raced it, I won 20 straight races over a three year period from 1988-1990, and was named The Greatest Endurance Athlete of All Time by EPSN. There have been huge gains in technology since the early years of triathlons to help athletes measure and quantify a lot of elements of getting fit and racing fast that I had to be figure out by simply tuning into my body. But every piece of the core training wisdom that I used is still the same.
