no train delays? :)

no train delays, weather was just perfect. I got a tiny sprinkle of rain for a few seconds during the TT, it was refreshing.

very windy though, our Aerolab derived CdA was worse by .02 than the last mopac tt, which was also a bit windy.

I believe it.
if you are used to crank based power meters, they would have read a wee bit higher

Not disbelieving what he posted - just can't believe how bad my position must be considering my power to speed.

And he listed that he was using a PT...;-)

Here's a link to Garmin Connect: http://connect.garmin.com/activity/133593648

I forgot to hit the stop button on the Edge 500 when I racked my bike but I exported the file to WKO and edited it to match moving time, and thus get average and normalised power.

2 things the OP didn't ask for that affect speed without regard to power - road surface and temperature. A large part of the course was on very smooth hotmix asphalt/tarmac (although a lot of it was on very rough stonechip surface) and the temperature warmed up considerably during the bike.

But you can just take Jackmott's answer - it suits me :-)

Again - not doubting you, more questioning my own position, etc. Impressed with the power to speed and wishing I could manage the same.

Thanks to my bike-fit specialist, Toby from BikeFit Asia. Absolutely no discomfort or neck/shoulder issues and as low as I can go without compromising power. Shorter cranks are next...

In fact, I'm blaming being *too* comfortable on why I wasn't concentrating enough to consume all my on-board nutrition on the bike! :-)

I can't see the pics posted from this site so apologies in advance if this has been done.

Try plotting ln(power) vs ln(mph).
Then add a trend line, it shows there is a log linear relationship.

The interesting cases are those not on the line, hill climbers, courses finishing at the bottom of a hill plus those who have better/worse positions.

I pulled the data at one point and tried to find a good curve fit and the best result I got was linear. I was expecting to get a good 3rd order polynomial fit due to the normal relationship between speed and power of a single rider (rolling resistance goes as speed and drag goes as speed cubed).

I think the linear trend is showing that the stronger you are or the faster you go, the more effort you spend on getting aerodynamically efficient. Or in other words, slower people may not spend as much time or cash on getting as fast as possible. But there may also be more going on in terms of the fast short course races vs the 56/112 mile legs in terms starts, stops, corners and hills.

Here is a recent workout:

***5x6 mile TT's w 1.5 mile recovery spin (it's a loop)***

-at an average of about 325 watts for all 5
-at an average of about 41.5 km/hr for all 5
-155 pounds
-Mavic Ksyrium front wheel, DT Swiss rear wheel with wired PT, vented helmet, Planet X Exocet frame

Very windy day, and the wind seemed to be hurting me more than helping me on the portion of the loop I was riding hard that day...I did these intervals on a less windy day at 43 km/hr a few weeks ago...not power meter that day though.

70.4" / 179cm. What's the relevance?

I think I need to lose 5kg to be where I want to be for IMC in August.

Just curiosity as I also have my power data from both races (Busso & Singapore) but mine are some 50-60W higher than yours. Esp. Busso, where I rode (last year) pretty much the same time as you my NP is 222W and AP was 216W respectively. So if we take some 10-15W each per helmet & bike, then there is still a difference of ~30-40W at the same weight; thus my question abt your height - and there is a significant difference of 179 vs 200. I am not sure whether that is the sole explanation of +30-40W but it made pretty much sense, especially on such flat courses like those two.

In this respect, it would be interesting whether you have any data from some hilly races (like LPT in Phuket, IM Lanzarote or similar) where the aerodynamics becomes less important and the kg/W ratio would be more comparable.

In this respect, it would be interesting whether you have any data from some hilly races (like LPT in Phuket, IM Lanzarote or similar) where the aerodynamics becomes less important and the kg/W ratio would be more comparable.


Here's my view of the differences. It would be interesting to see what Jackmott or others have to say about the direct comparison:

My Bike: 2010 Cervelo P3, Vision Basebar & brakes, Profile Design T2+ extensions. Sram Force bar-end shifters (fullSram Force groupset)
Your Bike: Cannondale Road Warrior 800 (2005) roadbike with road handlebars, STI, Syntace C2 clip on

My Wheels: 2005 808 PowerTap Sl with Aerojacket wheel cover, 2005 404 front, Vittoria Corsa EVO 23 tubs.
Your wheels : Cosmic Carbone SL front/back, PowerTap SL, Continental GP4000s 23mm clincher

My hydration config: 2 rear bottles, Speedfil A2 between the arms (nothing on the downtube)
Your hydration: 2 standard round bottles inside the frame

My Helmet: Rudy Project Wingspan
Your Helmet: standard road helmet

So the difference must be that I shaved my legs :-)

Joking aside: How smooth was your power delivery? Did you focus on an even delivery down-wind and into the wind? Did you have a lot of surges to pass people, did you accelerate hard up the few bumps and out of the u-turns? Did you slow down at the aid stations and speed up after them?

With only 2 bidons on board I'm guessing you took a handup at least 2-3 times in Singapore (to my 1). Apart from the obvious aero and rolling resistance differences in our setups and positions, I focussed on holding 180 -200W all the time, and only took a handup once. I can't see the picture you posted but my position is reasonably aero for my size. (ducks for cover from ST onslaught)


We could have had similar times but if you were pushing out more watts in surges and headwind legs, and I was laying mine down more evenly, it's quite possible that I'd have a lower AP/NP value than you.

For further comparison go here and do the calcs side by side: http://bikecalculator.com/wattsMetric.html

Enter in the same weight for rider but a difference of 2 kg for the frame (yours = heavier) Make sure you show yours as clinchers, and choose drops for yours (since you have them even though you're in the clip ons). Put in a 5km/hour headwind (net) The result is clear: same speed, bigger power output required by one.

20k ITT:

Time: 29:40
Speed: 25.0 mph
Power: 264 watts (261 normalized)
complaint: under paced the tt, had way too much left, last mile was over 300w, almost 400 by the line... FTP on road bike is ~280-290 for reference

Other: 163 lbs, 100 feet climbing on course (out and back course), 37 degrees, rain/sleet, < 10mph winds, 2009 cervelo p2, zipp 404 clinchers w/ wheel cover, butyl tubes, attack/force tires, no water bottle, aero helmet, skin suit, shoe covers, big warm gloves.

what does all this say about how slippery my position is? just curious about random feedback..

I'd say 25 mph at 260 W is pretty slippery. Care to post a picture of bike and fit?
