I have similar goals as well; I just want to be able to do big days on the bike and have a long term healthy hobby. SSB always seems to build me up but the moment I have some inconsistency (life gets in the way) in workouts or start going outside for fun rides, my fitness goes down significantly. I felt like despite doing a lot of SSB workouts, at the end of the season my base was shattered.
One of my goals over the next winter season is cycling consistency, and since there are no races on the calendar I figured this is a great time to to invest in 12 weeks of Traditional Base. The nice part is these workouts aren’t particularly taxing so I have time and energy to pursue my fun activities (skiing, fat biking outside) while remaining consistent on the bike.
I had success several years ago doing MAF style workouts by having a lot of low intensity volume. I’m going to try to recreate this and see where I land.
