I was reading this tread before heading home from work actually learned something. I have no idea about cycling technique, only that it involves pushing pedals around to propel myself forward. So on my way home from work I thought I'd try your suggestions of moving to an easier gear and increasing my cadence (a new word I have just learned). It totally worked! I was flying home! Next thing will be seeing how long I can keep it up for. My commute only involves a 2.5mile ride to the train station.
