At the age of 50, I've decided that becoming a triathlete sounds like a really good idea. Xterra for the most part or other off-road triathlon. I have a rather technical running trail at my home that I train on daily and I've been an avid mountain biker for several years now two thirds of my training is covered. The one third that isn't is swimming. Other than knowing how to swim, I have never spent that much time doing it. I'm a stickler for form and maximizing any training effort into quantifiable results. Therefore just going out and doing laps in the pool seems like the wrong place to start. Last thing I want to do is develop bad habits. So, the question is, with my very limited skill set in the water, but being pretty good shape, where is the best place to start my swim training?
