Well according to that, then i would have a FTP of 415, which i seriously doubt i have. My 1 minute is about 550-560. I think that my real FTP is more in the neighborhood of 300-320...maybe, though i have never done the actual test. ( need to get on that soon) Ive been trying to keep it only base miles recently and haven't done a ride under 3-5 hours lately.
Oh and just for reference, im not a sprinter. Im much more of a climber/time trialist. (is that how you spell that?)
