I was a beta tester for Zwift when there was only a small loop and ghosts. I’ve started using Rouvy a couple of weeks ago. My take based on the many rides I’ve done on both platforms is that Zwift is overly optimistic with its CDA estimates and for a given power, the speed seems often times off, at least on the flat courses. The only “real” course I’ve done on Zwift is the Alpe. There it seems to be pretty close. But on the flats I doubt it.
Rouvy seems to be the opposite. I think they make very broad assumptions for CDA and speed is underestimated. I rode Indian Wells today at low end tempo (267w) and didn’t break 58min on a net downhill course. On flat sections, I could match power and speed and they were off. Being 5’8’’ and 139lbs with a reasonably good position, I can usually hit 25mph at just about 220w.
With that said, I really like Rouvy, real courses, videos, and less crowded. I’ve only used the app on my Mac and didn’t have any issue. No crash etc. I think they’re nicely complementary apps.
I’ve been on ROUVY for just over a year and really like it. Real world courses plus opportunity to make my own is great.
Although the new AR is way off (slower at higher effort). Rode a course I created many times on original and it was close to reality. Rode new AR and wow felt like riding into a 20 mph wind the whole way. In fact rode outside for first time last week (WI weather sucking) rode this course with a 15-20 wind and was still faster into wind. So new AR has something off. using H1 as my trainer and noticed the power on H1 and my vectors has been off by 5-8 watts and used to only be 1-2 watts different.
Tried Zwift and went meh.
