I agree w/the OP; I've done TR ramp tests and 20' TP tests which puts my FTP at a level that is higher than what I think I could do for a solid hour. I also know that at an age of over 50 I will never have the courage or stamina to ride for an hour to find out what that number actually is. This said, I am confident that my FTP is lower than what a segmented test would interpret.

I disagree. there may riders/ametuer racers who can put out this kind of power; it is however an uncommon trait among most cyclists or to normalize things, it is highly doubtful there are lots of non-pros, young and old, who could ride at or above 4 w/kg for an hour long effort.

Now, I will tell you that my ftp is south of 300 and am happy to go on a ride with any formite to prove it |

This is not uncommon. Defining FTP as "your max output for an hour" is an extremely flawed estimate of the aerobic threshold. How long you can hold your FTP for is a whole different measure...

I was under the impression that by definition 1hr power is = FTP, if you can’t hold the power for an hour it isn’t your FTP? Like the above poster claimed he had a 300+ watt ftp yet averaged 260 watts in a 40 minute breakaway due to “factors”... this is what I’m talking about.

FTP is not one hour power. That's just a convenient way to think about it.
There is a trainerroad forum where they are running an unofficial ftp challenge - ride your ftp for an hour. There is a workout that is just one interval at ftp for an hour. Many people have done it. Who knows if they are sandbagging on the ftp number or not? https://forum.trainerroad.com/t/the-...enge/12430/113 Last edited by unterhausen; 03-18-2019 at 04:38 PM. |

aerobic threshold, otoh, doesn't have a precise definition. There's the power for 4.0 mmol steady state, ventilatory threshold, MLSS, etc. All slightly different. But the duration is baked into FTP Quote:
if i were to test solely for max hour power, i might get something else, but that effort per se won't help me do well in races (another thing focusing on FTP per se would miss) this is the part that few appreciates. Cost of marginal energy is not scaled linearly, b/c riding over threshold tips things out of a finely balanced steady state. |

FTP fluctuates with fitness.
Here's an example from a year of racing in my late 20s. I did a test in November after a few weeks off that put me at 240w, I did a test in the spring before racing that said 280w, and from a 1hr crit in July was 320w. 80 watts from peak off season to peak racing season.

I’ll just say I disagree w/the good doctor. achievable equals not achieve. for various reasons, but the biggie; most could not endure the pain/suffering of getting them to this level of fitness and this is the big rub!
