The issue, I suggest, is building a lifelong riding habit.
Take it slow, easy and flat to start. Ride areas you enjoy even if you have to haul the bike to them.
As the miles accumulate, start doing as much interval training as you want to do. As more miles accumulate, ride place you enjoy where hills are part of the mix.
By this time next year, you can easily find yourself a cycling addict who rides about as far as he wants.
