DancenMacabre said:Martin's mathematical model is detailed. Although I admit to not having all the parameters it requires handy, thus wondering if there is a simpler way to predict one's 2k-4k pursuit time given the more common details (Cda, weight, Crr, AP, 5s power, etc).
acoggan said:As a first approximation, take 10% off of the maximum power that you can maintain for the duration in question, and use that to predict your speed, and hence time, assuming steady-state conditions. That will get you in the ballpark...and unless you've got detailed data re. the track upon which you plan to compete, being in the ballpark is about all you can expect.
(Note that this approach assumes 1) that you are sufficiently fatigue-resistant to withstand the "hit" that initially getting up to speed will have, and 2) that you do a good job of pacing yourself.)
I bet it isn't.DancenMacabre said:I'm inclined to believe that 2k, given the higher expected contribution from anaerobic sources over the shorter time period, favors a profile w/high 1m power. Plus I'd bet pacing is more along the lines of all-out, sort of like a kilo.

DancenMacabre said:I'll have to give some thought as to which distance (2, 3, or 4k) most suits my characteristics. No doubt having high anaerobic & aerobic power are keys to one's success. Nonetheless, I'm inclined to believe that 2k, given the higher expected contribution from anaerobic sources over the shorter time period, favors a profile w/high 1m power. Plus I'd bet pacing is more along the lines of all-out, sort of like a kilo. Whereas the 3 and 4k will put more emphasis on maximal cardiovascular fitness & aerobic ability and pacing is somewhat more even. Conjecture, but those are my guesses.
True - it's a really nasty distance from that perspective and of all the distances needs more experimentation I think.acoggan said:DM did say "...more along the lines of..." and "...sort of...".
acoggan said:Ah. Well in that case, I'd be happy to crunch some more numbers if you want to send me the details in an email.

I really must find the time to write up that item about the chart comparing 2, 3 & 4km pursuit times to the power to aero drag ratio. I think I might be over thinking it - just get it out there Alex!!
