In reply to Dave B:
I don't use zwift, all my indoor riding is in erg mode so the only claim I am making is that I cycled x km's on a wattbike. Like I said above, it's clearly defined as wattbike miles in strava so no ambiguity.
If you asked me how many miles I cycled last year, I would say 4000km of which half was on a wattbike (for example). I don't see an issue with that, and I wouldn't think less of the wattbike miles covered personally...they are all hard earned in my book
