First, what do you consider "long distances"? To some that means a 50 mile ride, to me that means 24 hours a day.
Second, what kind of exercise have you been doing lately? If nothing, get going! Even walking regularly will help.
Third, build up gradually - aim for a distance increase of 10 to 15% per week.
I would consider 40-50 miles in a day long journeys.

yes I have been exercising but it has been jogging and lifting weights. So the jogging helps with cardio but the weights won't help my endurance will they? I plan to ride my bike to work (guess I gotta get a job first huh?) and it could be as far as 20 miles in one direction. I doubt it will be but I need to prepare
