I think it's better to ride 3 or 4 much smaller rides per week rather than two longer ones- if possible.
It gets you into the habit of just jumping on your bike
as part of your lifestyle, as opposed to 'planning' a ride like it was a special event or chore.
It also is less like something to dread or put off. Often you can do a 5 mile quicky even if you are tired or pressed for time.
What you want to do here is
change your lifestyle habits. Losing weight and gaining fitness will naturally start to happen as you ride your bike more often.
Make small do-able goals first. If you are successful at those, then increase your goals little by little. For many people, starting out with big goals just sets them up for failure. First get into the habit of setting and meeting your
small goals successfully and enjoying that feeling!
