That's really cool KSH. I don't plan on doing any racing, but I do want to get good enough so that I don't feel like I'm holding up my husband too much when we ride together. He hasn't been biking any longer than I have, but he's just naturally more athletic and faster. Plus, it's just fun to be getting reasonably good at something athletic. I'm a classical musician who was always babied and discouraged from doing anything potentially dangerous, so I've basically spent my life indoors... seated.

SheWhoBikes... I learned about these podcasts right here on the board. Check out Podrunner and Podrunner Intervals here: http://www.djsteveboy.com/mixes.html
and Pedalradio here: http://pedalradio.libsyn.com/

They are planned to go at certain speeds. Pedalradio and Podrunner Intervals have various speeds within the same track so it's like doing intervals. If you have rhythm and can pedal to the beat, it's a way to practice pedaling at a steady cadence. I've also biked with a metronome on to keep any particular steady cadence, but it's obviously not as entertaining.
