I just started a my second training program. Halfway through the first workout (on a flat course), I noticed the resistance was increasing. ERG mode says it’s on, but it gets harder and harder to pedal to the point that I can’t even turn the pedals in the lowest gearing combo. So I have to stop, and ERG says temporarily disabled. When I start pedaling again it’s better, but it almost immediately starts again. I tied the re-calibrate using the TacX Utility, and that disconnected the signal to my trainer, couldn’t reconnect, had to re-boot zwift, and lost my workout progress.
I’m using a TacX Flux S trainer, only a couple months old, with an Android Tablet (BLE signal - I know, I have an ANT+ dongle ordered.)
This was never a problem during my first 4 week FTP builder training program. What the F is going on?
