I’m just starting to think about swimming over the winter. Currently I have been swimming about 2500yds twice per week and 3000yds once per week. I just changed pools and I was planning to reduce the number of days from 3 to 2. However I was going to increase the volume per session to around 3600-4000yds.
Any negative impacts from fewer sessions but maintaining the roughly the same volume? I will still get the occasional weekend swim for another 3000yds but not very often.
Thanks.
It probably matters more what you do during your sessions. What were your avg. Workouts, and what are you planning on changing them to?

If you’re a moderately competent swimmer or better I’d say it will have little/no negative impact. In fact the longer distance may be beneficial.
Huh, swimming in the winter? 
I’m just going to apply a basic principle from other endurance sports and say that it’s primarily about total weekly distance, so no difference.
But what you may find is that each session results in more fatigue and that can either be good or bad. If your form breaks: bad. If your exhaustion results in you finding a way to reduce wasted motion and tension: good.
