    What about just raw power? Power to weight ratio does not tell us how fast you can ride on the flat and rollers.

    Very similar numbers but a Cat 3 in Upstate NY.

    FT - 4.67 w/kg
    5' - 5.82 w/kg
    1' - 8.73 w/kg
    5" - 17.09 w/kg

    5'6" and 60kg

    Well, it does give you a bit of an idea since weight tends to correlate with frontal area. Unless you're an extreme example (say, FT under 225w or over 400w) I'd wager w/kg is as good a predictor as any number.

    I wouldn't necessarily say that weight correlates with frontal area...

    Besides, isn't there another thread dealing with Raw Power?

    http://www.cyclingforums.com/t310978.html

    I know that I have posted FTP, weight, 10mile TT time and 40k TT time...

    Notice how you cannot predict my 40k time by FTP or w/kg alone?

    Aerodynamics has a little to do with it... :D

    Remember, it is still a brick... ;)

    No sooner do I write my stats down then I go and set new PB, 5mins is now 5.15W/kg, which is nice... Now just need to work on 1min power.

    You should, since it does.

    Of course the important question is does FA correlate with weight to the same degree that power does =).

    Better than nothing for sure, as good as any...shrug.

    Try a search for w/kg^.67 for a whole bunch of thoughts, without any clear consensus =).

    Here in SoCal this is what I'd estimate...

    In a small p,1,2 race (non-NRC)...

    10+minute climb you need 5.4ish to stay with the lead group (which will have 15-20 riders in it).

    5-10 minute climb, 5.8ish

    Sprint is of course as much about tactics and positioning as power, but there are several guys that can do 18-20w/kg for 5 secs, and 15+ for 15 seconds.

    In NRC races the numbers aren't that different, but there will be a few riders that will be able to accelerate briefly above those numbers and get separation.

    In 35+ races the numbers are also very similar (perhaps 0.2 less for each climbing duration), but the lead group will be much smaller (usually less than 10).

    I think for almost all amatuer TT's, aerodynamics are often the deciding factor. I'd say that in a typical, higher level, amatuer (i.e. p,1,2 or 35+) race, aerodynamics are a bigger factor in results than power (not that power isn't important, just that there is much more variation in how aero people are than how much power they can sustain).

    I would have thought that build would have more to do with frontal area than weight...

    Well, height tends to correlate better with frontal area than does weight, but 1) that's not "build", and 2) it's neither here nor there: this issue was whether or not there is a correlation between frontal area and weight, and several studies show that there is. Ergo, it is incorrect to claim that there is no such correlation (as, e.g., Warren G likes to insist), and that power in W is therefore a better predictor of level ground performance than power in W/kg.

    Southern California Cat2

    00:05 - 18.83w/kg
    00:30 - 16.17w/kg
    05:00 - 06.84w/kg
    60:00 - 05.30w/kg

    No results at the P,1,2 level to speak of yet, but only have 3 races at this level and my fitness has skyrocketed now that I'm no longer working 40 hrs a week and am sleeping 9 hrs a night instead of 5 hrs a night. According to smartin's data/experience, next year should be a different story hopefully.

    thanks Andy...

    I guess I will work on my nomenclature, as when I said "build", I was meaning height, weight, shoulder span, how the person carries their weight etc...

    www.dictionary.com - build
    9.the physical structure, esp. of a person; physique; figure: He had a strong build.

    I just don't get it. Had a lack luster year. Did fair in TTs. No places but at least in the top third in each race. For my cat 4 & Masters 40+ road and crit races though, I got dropped before each finish. Yet my numbers are for the most part better.

    FTP: 4.35 w/kg (actual 40k TT 1:00:43)
    5 min: 5.22 w/kg
    1 min: 7.71 w/kg
    5 sec: 14.62 w/kg

    Guess I need to ride smarter and continue to try to push those numbers higher for 2007.

    A match analysis might reveal that you ran out of matches.

    What % of FT is considered a match?

    I think Hunter is being a bit liberal there (I'd set limits at higher percentages, and I'd also have an NP limit for durations >10 or 20 minutes), but I think the important thing in talking about number of matches burned, or "matches per hour" would be consistency in measurement.
