Hi, I have a pretty basic setup with a TACX Blue Motion dumb trainer, Garmin cadence, speed and HR monitors feeding into a Macbook pro via an ant+ dongle, but perhaps crucially, NO POWER METER, so am dependent on the Zwift algos for best guess on my wattage. However I am reasonably confident that it’s in the right ball park having compared it to wattbike workouts done in the past. For most rides this setup works fine.
But when I try and drop the hammer and go flat out the watts peak at about 380 (my FTP is 335) and then drop off to about 350 as I go harder. I can’t seem to register a reading greater than about 380 watts. My hunch is that the ant+ feed gets overloaded the harder I go and without a power meter I will just have to suck it up, but any suggestions would be greatly appreciated.
