I've been toying with trying a triathlon, too. My main concern is the time required to train. My gym membership expires and I want to join the Y, which has a Masters Swimming program. The Y also has spinning classes and V02 max tests and such. My gym does not have a pool and frankly, I don't like going there (college age mostly, obnoxious music in every room, etc.)

So, I'm thinking about it...are two masters swimming sessions per week adequate for a sprint tri? I don't see how I can fit four swims per week into my schedule, but I could do two.
