Wondering if the spreadsheet model is available to help break this route into segments.

Converting my older Aluminium road bike with proper TT handlebars/shifters sounds a lot more attractive now.<BR/><BR/>Any comments on how you derived the ideal pacing strategy? I am assuming there are some interesting mathematics behind it?Unknownhttps://www.blogger.com/profile/09556986865887434676noreply@blogger.comtag:blogger.com,1999:blog-35788819.post-58848036160890198002009-04-07T19:00:00.000+10:002009-04-07T19:00:00.000+10:00DanI just use a screen capture tool* to save the p...Dan<BR/><BR/>I just use a screen capture tool* to save the pics to my hard drive then use Blogger's picture upload tool.<BR/><BR/>*I use Faststone Capture but it also works if you use the PrintScreen button and paste in MS Paint, and crop the picture to suit.Alex Simmonshttps://www.blogger.com/profile/00698332397074026424noreply@blogger.comtag:blogger.com,1999:blog-35788819.post-14217828305266317892009-04-07T18:58:00.000+10:002009-04-07T18:58:00.000+10:00Mass of equipment has a much smaller impact in TT ...Mass of equipment has a much smaller impact in TT performance, unless of course the TT has a lot of climbing. <BR/><BR/>In this instance, the two bikes weighed the same anyway (I hopped on the scales while holding each and there was no difference).<BR/><BR/>What matters most is the power to CdA ratio.<BR/><BR/>But for the sake of argument - what would the performance advantage be on the 25km Calga course if the TT bike was 1kg lighter (all else the same)?<BR/><BR/>A: 6 seconds.Alex Simmonshttps://www.blogger.com/profile/00698332397074026424noreply@blogger.comtag:blogger.com,1999:blog-35788819.post-44786679738393753262009-04-07T17:37:00.000+10:002009-04-07T17:37:00.000+10:00Hi Alex, this is my first comment on your blog but...Hi Alex, this is my first comment on your blog but i have kept on eye on it for a while and i think some of your write ups are absolutly fantastic. I do have one question though, how do you insert screenshots of your training peaks files as this is something i am trying to do but cant seem to be able to.<BR/><BR/>CheersDan Billnoreply@blogger.comtag:blogger.com,1999:blog-35788819.post-16550395449845033732009-04-07T08:29:00.000+10:002009-04-07T08:29:00.000+10:00Thanks Alex.Was there any weight difference betwee...Thanks Alex.<BR/><BR/>Was there any weight difference between the TT bike and the road bike you used last time? Does that play a part in the scheme of things?<BR/><BR/>Also - I'm really interested in the pacing aspect. Do you have any references on this? Intuitively, I've always felt going a little harder up the hills at Calga then slightly easing off on the descents seems to work well, but I am only guessing.<BR/><BR/>Then of course, there is the bastard of all time right at the end, Blood Hill. :)<BR/><BR/>I got my best time at Calga when I really hit Blood Hill pretty hard, but boy was I in agony after that!Unknownhttps://www.blogger.com/profile/09556986865887434676noreply@blogger.comtag:blogger.com,1999:blog-35788819.post-3909232539161361082009-04-06T20:48:00.000+10:002009-04-06T20:48:00.000+10:00Oh I can readily put in another power number and g...Oh I can readily put in another power number and get an indication of the time reduction. For instance, if I was capable of say, 5% more power, my time would be about 58 seconds less on that course.<BR/><BR/>As for the value of a disk wheel or an aero helmet, well until I test the difference in CdA, that's a bit hard to be quite so specific.<BR/><BR/>I will have an aero helmet on loan for my next TT at Mooball. I doubt I'll have a disk though.<BR/><BR/>But for instance let's say that combined they provide for a 5% improvement in total CdA. That would equate to a reduction of 32 seconds (at same power). But I don't know the actual drag reduction that such equipment might make in my case.<BR/><BR/>If I could produce 5% more power and achieve a 5% reduction in CdA, then my Calga time would be reduced by 90 seconds, just breaking into the high 39-min mark.Alex Simmonshttps://www.blogger.com/profile/00698332397074026424noreply@blogger.comtag:blogger.com,1999:blog-35788819.post-46998447840223487692009-04-06T20:19:00.000+10:002009-04-06T20:19:00.000+10:00Great post Alex - best of luck for the Mooball TT....Great post Alex - best of luck for the Mooball TT.<BR/><BR/>Just curious - do your models provide any rough ideas in time reductions as average power goes up on this course, assuming everything else is equal? <BR/><BR/>For example, say your average power in a few months increased by x watts. How would that translate to time at Calga?<BR/><BR/>Now I know this is asking for real rough and rubbery numbers, but do you have a feeling how much time would be saved if you had a rear disk wheel and/or aero helmet?<BR/><BR/>Thanks for the great post!Unknownhttps://www.blogger.com/profile/09556986865887434676noreply@blogger.com
