It depends on your background. Some riders reach back to their high school or college days when they were in some kind of competitive sports program like running, swimming, or club sports.

At age 40 we come to grips that it takes longer to get in shape and takes a bit of effort to stay in shape. The bike riding thing is a bridge that connects the many good thoughts and memories as a kid riding on his bike just having fun.

When riding keep in mind that you are undeniably entering a new phase in your life and you need to cross this bridge.
