I don't set an annual goal for miles, but I do try to schedule a long ride every year that I need to train for. I don't care how many miles I ride during the year, just that I am able to comfortably ride in that event. This year it was Tour de Cure ride with rolling hills. Most years it is a flat MS ride with multiple ride options from 25 - 100 miles. I don't ride in bad weather, at night, or when it is under 45 degrees. I ride for fun and not for speed. Don't worry about the goals others have set. Just enjoy riding your bike your way. I know from experience that when you try to meet someone else's goal, cycling becomes something you dread instead of something you enjoy. As long as you aren't racing for a sponsor, then do what you enjoy! As you ride and get more fit, more miles will come naturally. If you want to increase your miles so that you can enjoy longer rides, then add a few miles on each week until you are able to ride somewhere you want to go, maybe to the end of a greenway trail or to participate in a charity ride somewhere. Most charity rides have multiple options for miles - anywhere from 10 mile rides and up. It is much more fun to set a goal to be able to complete a ride to a particular place than to set an arbitrary number of miles for the year.
