This morning I seem to be suffering with this bug (anyone else?), I found myself doing up to 100kph for normal effort levels - I could do 50kph on the flat @100 watts and no draft. I had to quit several events which was very frustrating.
I’m running Zwift on a PC - Win10, I’ve removed and re-installed, tried two different pwr sources (Kickr5 & Garmin S3’s), my numbers are right in terms of watts - but the speed is crazy.
