spin class, with POWER

Did my second to last spin class tonight, but my first using my PowerTap. You can see below in the graph the different sets that we did over the hour long workout. The last set before the cool down were 3 30 second spinups, increasing cadence every 5 seconds. I peaked out at 565 watts! SWEET! I again came out at an average power of 245 watts, so since I have hit this number 3 different times, I guess I am gonna use this as my functional threshold (FT) wattage.
