Hi Brian, and welcome to the Forums.
It helps if you have a specific goal in mind, that way you can structure your training around achieving that goal. "Just riding" is not going to help you improve that much.
Remember the three important aspects of training:
- Duration
- Intensity
- Frequency
Duration improves endurance, Intensity improves power, and Frequency improves your rate of recovery.
Read around the forums, do some research, and ask questions regarding what you've read on specific things.
Happy riding!
