It would be nice to have a power corrected mileage output to Strava for the workouts like Zwift has. Right now if I do a workout in ERG mode in my small chainring at 200W vs big chainring and 200W my mileage reported will be much different. Can we get an estimated correction factor to these numbers so at least I can kind of compare the effort \<-\> miles relationship?

They already acknowledge it’s an issue in ERG mode.

> TrainerRoad may eventually add a physics model that provides more reasonable estimations of speed indoors. However, this is not something that’s currently on our roadmap, so we don’t yet have an ETA for this feature.
