I haven’t been on a bike for a long time and I wouldn’t consider myself as a beginner. I have a Tacx Vortex Smart-Trainer. The trainer was calibrated correctly using the Tacx Utility. On my first ride through London today (27.04.2020) I have an average speed of 30.1 km/h and a maximum speed of 79.1 km/h. My average power was 237 watts, my maximum power was 416 watts. How on earth can I be so fast?
I’m using the Zwift App.
