I wouldn’t think any changes would be needed in USRPT because of the primary focus of USRPT to be able to allow for recovery workout to workout. With the additional time between water practices, this would seem to be assured. However, what is something to be mindful of is the additional work outside of the pool interfering with practice performances. Always keep focus on technique at race speeds. Dr. Rushall published a good paper on the pedagogy of stroke mechanics that you may want to investigate. You can slice-and-dice distances however you’d like. It’s all relative to what they can handle, and progressively increasing the amount of time/distance done at race speed. Do them relative to what they are capable of to start with, and this will manage itself, so long as you do not overdo it as you build this up. Be willing to stop or even regress a bit if you see issues, and keep track of what’s been done, so this can be quantitatively be measured. We never did anything in sense of a race-pace repeat, that was more than 75 meters (SCM) and had no issues even up to the 400/500 free.
