My understanding of polarized is hard days hard, easy days easy. These ride look like they are the opposite of that. It’s a bit of everything. If you really want the best outcome to a training plan you have to really stick to it in my opinion.
That said, I also believe that rides like these can be really good to just stay motivated and enjoy riding your bike. It’s all about finding that balance. As long as they don’t negatively effect your hard days from the plan, I see no real problem.
