Calibration Right but Zwift is Slow


I’ve Calibrated my Tacx Flow T2240 Interactive Turbo Trainer and I’m doing 30mph+ but Zwift only has me doing 8kph (It’s flat) i’m defiantly doing more than 8kph.

any ideas?

In settings,what is trainer difficulty set at?
How many watts are you doing at 8 km/h?

Can’t remember from top of my head. what should it be set at for a beginner?


I think is it set at 50% as default

Zwift use your power (w) that you generate to calculate your virtual speed. So your wheel speed and Zwift speed will not be the same.

As Tomas said, what was your power and cadence.
