I have seen a couple of upgrades since starting Zwift. The other day, the tension on the trainer kicked in on a downhill - it was the strangest thing. Did not think much of it until I tried to do a couple of FTP test. I could barely push the trainer at 265 watts for the 2 minute warm-up section. The setting for trainer difficulty is set to “off”. My other recent FTP tests were all over 200 watts for the 20 minute sustained effort. I doubt I could even hold 175 for 20 minutes today. I even uninstalled the software and re-installed. Same thing happened the 2nd time. . The tension on the trainer is consistent i.e. 2.2 to 2.6 as I always test it before plugging in and starting the trainer. I might be tired or over trained, but the whole thing just seems odd. Any ideas or thoughts would be much appreciated.
