After finishing mid-pack throughout the 2007 racing season, I purchased an iBike and began training with power. In 2008, I won 5 of 6 races. Training with power made all the difference. Prior to the iBike, I trained with HR. It was better than just training by feel, but not nearly as motivating and effective as training with power. When doing intervals, HR is a trailing indicator that takes a while to ramp up in fit individuals. Power is RIGHT NOW. I found it much easier to do 350w intervals rather than 165bpm intervals.
Riding, training, and racing with power has made a HUGE difference in my enjoyment and results.
