I can tell you how I achieved that--by taking my cycling computer off my bike and othewise not tracking miles, speed or etc. Sometimes I miss having a big mileage goal (and meeting it), tracking my progress, etc., but it was something I ended up trading off for a bit of extra sanity. Granted, some of the things that forced that change have, themselves, since changed, and it might be time to for me to revisit more specific goals and the means by which to track them, but I don't regret taking a big step back at the time. Bodies change, lives change, interests change, goals change. In my mind, strong are the flexible.

So, go with what feels good, body mind and spirit. God knows you're kicking butt with your current routine. I see no reason for you to rock that boat unless and until you're ready to.
