I don't think you should have guilt for not "feeling" like riding. You are doing other things. As long as you are doing something to keep yourself fit and enjoying THOSE things. By the time next season rolls around, you might find yourself longing to be on the bike more. Or maybe not. Variety is good for this very reason. I think it's normal to get burned out on something you do so much of ... even if you have loved that thing so much.

My husband runs as well as rides. He goes through periods where he does both fairly equally, or one or the other predominantly. Right now, he is in full on running mode and has hardly ridden his bike this year, his extremely nice Cannondale System Six. He has no guilt, nor should he. It's there when he's ready to spend more time on it.

If you get to a point where you want to try to motivate yourself to get on the bike consistently and find a way to really love it again ... other than the already suggested "ride for fun" and "notice the scenery" and all of that, which is great .... challenge yourself in ways that you haven't really done before (if that's possible ... not sure of your history). If you have always been about building up mileage, then switch to being about your speed. Going shorter distances at a faster speed ... or even longer distances at a faster speed. Or work on being the best climber you can be. Maybe do a time trial if you never have. Explore places to ride that you never have. Think of goals that would be different than the goals you have had before. Maybe try mountain biking if you haven't done that.

My husband does road biking, mtb, street running and trail running ... oh yeah, and triathlons. He mixes it up and gets to experience a lot of different things that way. I, for now, am all about the bike. It's new enough to me that I'm in no way burned out.

Another thing is to find good people to ride with, unless you already have this. I ride at least twice a week with a friend of mine. It motivates me to get up and get going in the morning when I know I have my friend meeting me to ride and it's so much more fun to do it with her than by myself. On the weekends I look forward to the club rides where I'm beginning to know more and more people and socializing with them, challenging myself to keep up with the faster riders. Or for you, it might be challenging yourself to hang back with the slower riders and take in the sights!
