Your age - would suggest you would want to try to ride as well as you did ten years ago. But, if you had no fitness level then, I guess you should be setting new fitness goals now.
In either case, improvement in any sport is easier when the athlete takes stock of his/her exercise volume and applies measured efforts for measured session lengths and frequency. These routines require self discipline, that's why its called "training."

You have to ride fast to get faster. You have to ride often to be able ride longer. Good Luck.
