Time Trial / Time Trialling / TT

Train on perceived effort, measure the effects later. There is no need to know how much power you're producing. You do your FTP test on PE anyway, don't you? So if PE is a good enough guide to how hard to try on the one occasion you actually need to measure power, why is it suddenly useless on the other 41 days?

Train on PE, measure the effects later? Measure them with what? Race times? That's useless as conditions vary.

Do you chart all your rides and their PE scores? Do you honestly think PE is as good as power for measuring a ride's intensity? Studies have been done that show PE is not good at all - in heat for example. Do you know how many days of x PE you can do before you're likely to get sick without rest? There's so much useful information in WKO I can't believe you've dismissed it. You must be one of Hunter Allen's jilted lovers or something? :P
