Last night I did Zwift on the Richmond course which is about 10 miles with just under 500 feet of climbing, all in the last few miles. I turned and burned on the first lap setting a new PR at around 27 minutes. I flopped and flailed the second lap at 30 minutes but Zwift moved my FTP up to 237w from 229w based on the effort. My average for the hour including warmup and cooldown was 215w. I may try a flat course for an hour just to see.

Like the OP, I'm skeptical-- and I don't think it's just people inflating their FTP online. There is big money to be made on indoor cycling, and part of capturing that market is making people feel good about themselves. If you're marketing an erg trainer, do you think a customer is going to feel better about your product if they think they just crushed a PB and it spits out an impressive FTP, or if on the other hand it reads low and they leave feeling weak and deflated? Advantage: calibrate a little high. I'm not claiming a gross error, just that over a few product cycles, in a competitive landscape, I can see how power values could creep up a few %.
Then there's the test methodologies going the way of 6 minute abs. The result is it's easier to train for the test-- the shorter the test, the more you can train for it anaerobically (cue recent cycling magazine articles about improving FTP by lifting weights). A bike at the gym even has a built in 5-minute FTP test--LOL. The two factors above can be plausibly denied by the consumer-- "I'm just doing what it told me to do/reporting what it says." Add in the social media factor, and it's pretty easy to see how people would cut the corners on these tests or just straight up inflate the number. So yeah, I think the typical reported value is high, whether intentional or not. That said, I don't think 290-300W is all that crazy for an 80+ kg guy who trains for steady state. I might even be able to relate. That same guy will get smoked in any type of bike race that doesn't involve a flat TT effort. |

Heh.. I forgot to mention I tried Zwift on some fancy pants trainer at an LBS recently.
The bike was a 54cm, 1-2 sizes too small for me. Wrong size cranks, wrong seat height, I was wearing jeans and the bike had flat pedals and I had sneakers on. I.e. everything setup for me to make less power than normal. I'm really out of shape right now. Get on and immediately it's saying 300+ watts giving a moderate effort not warmed up... really suspicious. It was probably a lot closer to 200. It'd be REALLY easy to be clueless about calibration. Who knows. It was a direct drive trainer so it shouldn't be off that much. |

a guy i ride with, well we start rides with along with others in a big group at the same time, has logged +320W average power rides of 90 minutes on strava using a powermeter to capture data. it's not a proper FTP test, but he's doing this power for longer than 60 minutes so it's legit.
some people did a nice job of picking their parents *and* training to do something with their gifts. Quote:

But I wasn't talking about the initial spike.. my Stages does that outside for sure, so does my Tacx IIRC. This was like a few minutes, long enough to stabilize. I rode it long enough to get to try the video game. I was definitely riding it, I was starting to warm up, the readings just seemed high. Just made sure to quit before I started to sweat. |

I never said I don’t think anyone can do it, I just think it seems like less people have a 1hr power in excess of 300 watts than many sources would lead one to believe.

I quickly discovered this too. My rides go into my Strava and for fun I'll look and see how my 28,346 ranked sprint stacked up against the top 10 and see that they are all tied at 52 mph. Then there's the guy who did the 5.6 mile hilly loop in 12 minutes. My best sprint on Zwift was at 990 watts but some guy still went by like I was standing still. I compete against myself and so far I'm winning.
