While not wholly applicable to training for the swim leg of a triathlon, there are aspects of the training that could help triathletes get better results from their swim. The big takeaway for triathletes is that it is better to do shorter, faster repeats with better technique than to train long, slow swims where your technique breaks down. I see too many tri-coaches wanting their athletes to do regular 1 hour straight swim sessions, 10x400 over and over again and in general long, slow swimming where poor technique is ingrained in the stroke. My observation is that most of the tri-coaches have either running or cycling backgrounds and they are applying those principles of training to swimming; it doesn't work well. That is fundamental misunderstanding of how to get better at swimming. The important highlight of USRPT for a triathlete is that technique is the most important aspect of fast swimming, especially for a beginning triathlete, coupled with generating a "training effect" (hard swimming) while maintaining proper technique. This notion of training and technique linked together can't be stressed enough. You cannot separate out technique from training and expect to get faster in swimming.
