Pre Fatigue & FTP Testing

dan4280

Ah the perennial subject of FTP........

I have started using the 20 minute FTP test. I do a 20 minute warm-up then 5 minutes pre-fatigue at 120% of my last FTP result and then a 10 minute easy spin. Then I do 20 minutes all out and take 95% of this result.

My curiosity is around the pre-fatigue bit. The reason I chose 120% is looking at Coggan's table it looks like he basically says you can hold 120% of your FTP for 5 minutes. What do other people do for the pre-fatigue?

If I follow this I guess every time my FTP improves I will also have to up the pre-fatigue wattage. So last time I did the test I had an existing FTP of 241 x 1.2 = 289 for 5 minutes. I then held 268 for 20 mins to set a new FTP of 254. So I guess next time I test, my pre-fatigue has to be 254 x 1.2 = 305 watts.

Any thoughts? Maybe I'm getting too much like rain man with the numbers.

I had to look it up.

FTP = Functional Threshold Power

As for Coggan's table, I can't be arsed to look that up too.
