I love to swim sprints in a masters meet but I also have enjoyed doing triathlons. It is very difficult to train for both. I'd love to hear from folks that compete in both masters meets and triathlons to learn how they balance training and competing in both.
Swimming crawlstroke in a wetsuit is incredibly easy compared to training butterfly. My training strategy has been to let my biking and running comprise my slow aerobic training. So in the pool, I work mainly on butterfly, and to a lesser extent, medley. I don't do crawlstroke sets in the pool. I do very little open water swimming. At triathlons I use the swim as a warmup and have been first out of the water more than once. At Masters meets I am prepared for the events I actually care about, fly and medley.
