Speed barely changes regardless of Watts

[ianlewis23]

I just created my first workout on My E Training, to use with my Drivo. Despite the workout moving between 130W and 270W at different intervals during the ride, my speed only ever changed between about 30kph and 32kph. I know from reality and from Zwift that at 270W I would be moving a lot faster than 32kph. My weight is correct in the settings.

Can anyone help? At the moment this means that my rides are a lot shorter in distance than they should be.

Thanks
