Interval training is a key to making improvements in cycling. Using the PowerTap maximizes your interval training by ensuring that you are training at the correct effort for your distance. The 20 minute interval, while seemingly simple, can be an efficient way of improving your 40K to Ironman bike splits.

I have been training with power on the bike for several years now but switched to the PowerTap earlier this year. I knew that the power meter I had been using was measuring too high and was not terribly consistent, so in my preparation for the Olympic Trials I wanted the most accurate information possible to finely hone my biking for that race and subsequent races this summer.
