I’ve read in several places that there is an “optimum” W’ for a male road cyclist in the 14-18Kj range Very well-trained male cyclists do well with W’ values in the low to mid 20s. For females, optimal W’ values are around 11 to 15kJ for moderately trained and 14 to 18kJ for well-trained cyclists. …

Just beware that different CP models will give different W’ results, with the original 2 parameter model giving the lowest estimate, Morton’s 3 parameter the same but the Peronnet-Thibault model is quite a bit higher (which is the model used in WKO, and is similar to golden cheetah’s extended CP, I’…

I will preface this with saying I am a relative noob to cycling with only a few years experience. I have wandered a fair ways down the rabbit hole of this data though. I feel comfortable speaking to the math and the software but I am in no way qualified to speak to the training or what you should …

Intervals lists my W’ as 9000, I think that was pulled out of Golden Cheetah about a year or more ago which probably says how often I trac that metric.

According to wko5 mine moves between 10-13kj. U23 females can outsprint me so might be accurate.

Different tools use different models. And they need to be fed some maximal efforts, and as Tom Bell explained in the BikeRadar article one advantage of CP is you only need a couple of (shorter) max efforts. My primary analysis tool is WKO, but I do some comparison against Xert and Intervals. In pra…

thanks, and well that was interesting. Edited Xert to 1125W / 16kJ / 270W and it resulted in 230W lower threshold :rofl:

16kJ with a peak power of 1125W is possible but unlikely. TP of 250W, HIE of 24kJ with an LTP of 190W is likely a better representation, assuming 1125W is real. One check you can do is to make this calculation: (HIE*1000)/(PP - TP). A value of about 30 is most common. There was a post on the FB…

Thanks. FWIW I seem to have high PP and ok long TP, while relatively weak from 10-sec to 5-min. Lately I’ve been doing a lot of 2+ hour endurance rides at 190 so that LTP seems reasonable. In particular 30-60 second max/hard efforts I find quite challenging, and if its more mental than physical I ca…

Looks good. The best way to work through this is to “just ride” on Xert and let your breakthrough moments help characterize the signature in terms of how they contribute to power. Ultimately the signature needs to identify MPA and thus breakthroughs (isn’t this all the counts?). I really don’t lo…

What is your W' bal(/anaerobic capacity) in Kj? Did you work to change it?

numbers from here: WKO5 is here and it looks... different - #537 by WindWarrior and you can see Xert maps me to a modeled curve at higher 1-sec power and lower threshold power. Lopsided in favor of a higher W’
