Power meters are a great way to train...if you have a spare grand or two laying around. Fortunately, for those of us of more modest means, there's the CycleOps Powercal. This innovative little computer uses your heart rate and a special algorithm to determine how much power you're putting out. And the best part is, it costs about 1/10th of a traditional power meter. Just pair it with your power-meter compatible cycling computer and you're good to go.
