I've never felt bad about short or long rides. I just do what I have time for. Thankfully I've been getting in 40+ mile rides every other day for the last three weeks. Though there might be a 14 or 22 miler in the mix too.
Other than getting more mix to put in my bottles or carrying extra bottles, ride prep is the same for me. It's the making time for longer rides that is the b-word.
