I want to share my experiences so far with TrainNow. I just started Sustained Build MV. Took a 2 week “break” after SSBMVII and focused on more base/tempo training, including Haute Route in Zwift. I was also dreading the increasing time and intensity of sustained build, which was part of my procrastination; and then TrainNow/AdaptiveTraining was announced. So I’ve been modifying the standard plan, substituting whatever TrainNow suggests for VO2 intervals instead of the standard Tuesday workouts which tack on 15 min of extra aerobic, seemingly just to increase TSS. Trying to do longer Z2 rides in Zwift (literally just a custom workout with 2 hours of 5 min Z2 intervals while I grind AdZ).
1st workout suggested was Grassy Ridge +1 (.85 IF, 68 TSS) which I easily conquered while upping the the intensity to 110%. This week, TrainNow came back with Ansel Adams -1 (.97 IF 94 TSS). This one felt about right, and I didn’t feel the need to adjust the intensity.
