Good job swapping out the saddle. Strongly consider the same for pedals. Also something to catch sweat.

I have a cheapie mag trainer and rollers and go back forth between them. No Zwift. If I want more resistance, I just pedal harder/shift gears. Works enough for winter (where I'm just trying to maintain some semblance of form).


I go between http://thesufferfest.com/ and watching Lord of the Rings/Star Wars movies. Sufferfest never fails to completely engage. They're hard. I bought individual videos before they went to a subscription model.
