Take a look a TriathlonExecution.com a new endeavor by the coaches at Endurance Nation (EN) to specifically address race execution. I know there is NO other site devoted to how you actually execute a race, and maximize all the time and effort spent training.
All I can say is that in all my years of training, no other coach, no other plan, no other anything ever dealt with race execution as clearly and as thoroughly as Rich and Patrick at EN. That final piece of the puzzle--the execution--is what secured my 1:35 PR at Ironman Florida last year. Absolutely no doubt in my mind about that. It's key to maximizing all the hard work and time spent training to a racing peak. Do yourself a favor, and see what you can learn!
Happy training this weekend. Can't wait to ride long today!
