Reply To: Training for the IM
I think you are on the right track. To help you out I’m just going to post a quote from Dr. Rushall.
Even those who swim individual medley races should practice each stroke independently incurring training effects of the particular nominated stroke for the set. When practicing skills, time should be allocated so that individual medley swimmers can have substantial repetitions of turning from one stroke form to another. Those turns should also be practiced in blocks of substantial numbers of repetitions so that learning can occur. A suggested
minimum limit of skill trials would be greater than 15. Fleeting exposures to skills, such as four trials, are insufficient for any credible learning to occur
