I noticed today that TrainerRoad claims I was rolling along at 26 or 27 MPH when holding something like 185 watts, lol. This, of course, made Strava read that I did the work of riding 25 miles in an hour, lol(!!).
Heck, if I could expend only 185 watts and maintain 26 or 27 MPH, my sprints at 1000 watts would be legendary.
I take it that some setting needs to be adjusted with the app. IIRC, I went for the suggested wheel diameter during the normal set-up (at least I think it may have asked me that) - though I’m on a KICKR5, so no rear wheel used, just the cassette. My weight is correct. It did not ask me for my height I don’t think - taller people being less aero and all that.
