Talking While Riding Is Hard
#51
If you can do 2x20's at your FTP then I'd say your FTP is spot on. If not, then I think you might want to throttle it down or up as necessary.
A friend of mine did the lab test to determine his FTP. He backed it up with a 20' to verify the accuracy.

Sorry mate, but I think you're wrong. Anyone who can push 300 watts (120% of FTP) for 12 minutes continuously does not have an FTP of 250. Especially if they can do it back to back during an interval session. The first interval I averaged 283w, the second one I averaged 275w. Even using conservative estimates I'd be at 250-260w which means I'm not grossly overestimating FTP. I have access to a lot more of my power data than just these two rides. Normalized power over the course of the ride where I am is useless for determining FTP.
In any event none of this explains why I'm getting winded riding at 100w+ less than these numbers. But I guess we're well past that point...

You know, we must all be idiots, Dunbar. It's clear that you understand it all better than us. For example, whereas we think you're out of breath because you're not actually riding in Z2 when you think you are, you have a much better explanation which is.....
....what exactly?

So if I ask you where Los Angeles is, and you tell me "it's not in Europe", you would consider that to be a correct answer. And it would be correct!

2. I showed you direct data from my profile where my FTP has never been 280. How do I know? I tested.
For some reason you're not wanting to either test or post any previous test results. Until you do that anything you say about your FTP is a guess at best and horribly off at worst.
Seriously....been working with athletes and power data for 4-5 years now roughly. Run computrainer classes, work with multiple qualified coaches....
Just do a test.

Andy Coggan's Seven Deadly Sins
How to determine your Functional Threshold Power
In decreasing order of reliability:
- from the average power during a ~1 h TT (the best predictor of performance is performance itself).
- from the power that you can routinely generate during long intervals done in training.
- using critical power testing and analysis.
- based on normalized power from a hard ~1 h race.
- from blood lactate measurements (better or worse, depending on how it is done).
- from power distribution profile from multiple rides.
- from inspection of a ride file.

Have fun. You asked why you were out of breath and don't like the answer that all of us are unanimous in saying. You're FTP is lower than you think it is. It explains the trouble breathing. The only way to refute that is to take a 20 minute test. Take it and post the data. If we're all wrong then we'll all learn something and move on with our lives.

You're entitled to your opinion. I'm mainly taking issue with your vehement insistence that my FTP must be 220 (or whatever your latest estimate is) when my data suggests otherwise. There are many ways to estimate FTP:

All I've learned in this thread is that we should probably just stick to talking about which set of carbon clinchers to buy in the 41. I definitely will not be coming here in the future seeking medical advice...shudder...

So....you haven't ever tested and despite using a power measuring device for everything you don't have data the data we can use to establish your FTP.... but somehow we don't know what we're talking about...

I admire you. You encountered a crowd who all thought they knew the answer. They claimed to have much more experience than you. They tempted you with suggestions. But their answer didn't agree with your one pure truth. And you had the strength to reject their teachings.

Unless you have some serious respiratory illness, you've overestimated your FTP. Just do the test brah.
[MENTION=190826]Dunbar[/MENTION], PM me and I can give you some good locations in SoCal to do the test. I have a pretty good climb near me that I normally do my 20' intervals on.

You'd learn a lot more if you didn't come into it just looking for everyone to validate your flawed premise (which is what exactly?). It's not like there's dozens of possible explanations. You either have an undiagnosed respiratory issue (which you denied), or, you've overestimated your FTP. What else could it be? You've been provided with a solution (test) which could help narrow it down EVEN FURTHER, but you seem intent to stick to your guns with some OTHER unidentifiable explanation (a second shooter if you will). You're beyond help at this point.
