Hi @xflintx, this was a non-ZRL race where 18 riders (myself included) had no data:
Race zid=1372087
My profile z=834206
My other ‘no data’ ones are ZRL races and as stated above we don’t see the WTRL data so zwiftpower is our sole source of information on managing our rider categories and trying to avoid DQ.
As mentioned on the other threads (eg: zp critical power issue) the critical power I have been getting has been wrong anyway (critical power data not matching the fit file data).
Cheers
