Well looks like 2013 was still quite a bit faster for the first 55.7 miles.

Thanks for putting these together, seems Skipper was about 20W lower in Kona than IMUK.

So Angela Naeth put out more power than Callum Milward and went 6 minutes slower? Something doesn't seem right about those numbers.

Callum's powermeter is f'ed. I keep meaning to tell him at races. He posts a ton on Strava, and his power:speed is always so absurdly far off as to be impossible.

What about Tim Van Berkel? His 231 W can't be accurate either.

Berks is pretty light. I mean, maybe it reads a bit low, but I don't think it's that far off. He only weighs like 145lbs.

How much lower do you think? I of am of similar weight, similar gear, and (dare I say) quite similar position and I'm nearly a mph behind at 231...

1mph ~= 650sec over 180km ~= 10min over 4.5hrs ~= 25w difference.

If his reads say 5% low, that could easily explain the difference. But "similar gear" is a tough comparison...

I am ~7lbs heavier than Berkel. I ride 180k at the same power as his Strava says yet no where near as fast 22-23mph. Gotta work on my aero. Also a bit of a reality check that I almost without doubt over biked.

I learned a long time ago that the only pertinent information you offer is found within the last sentence.

Nice overview!

I think this really shows the difference in dynamics between the mens and womens race - check out Angela Naeth's power-file vs the top men. Naerth's powergraph looks just like a ride on the trainer - dead steady output. Compared to this the mens powergraphs look like road-races, with a lot more surges and coasting. F.ex- FVL has a top 1min power of over 450w and top 5min power of over 370w! That's pretty rough!

This is interesting. I tend to compare MY power numbers to MY power numbers. I so often see power numbers that just don't make sense (at least compared to mine). So, whether my meter is right or not (I think it is very close) at least I am comparing my apples to my apples.

Last I knew, he rode Stages, sooooooo......

Unless you get a new power meter, then it will not be apples to apples. So it is a good idea to have an accurate numbers.

I must be a barn door in the wind. I weigh around 145 as well, but it takes me pushing 250-260 watts to average 23mph, let alone 24.4.

My FTP as last tested was 280 so pushing 250 watts for anything longer than an Oly is not really part of the picture.

Yep you are a barn door. I am bit under 140 and I can do 23.1 with less than 205 watts (I do not have data on me, but I believe last year at nationals I did something like 23.2 on 195, the 205 was on a much hillier course).

Hmm... excuse to buy a new bike? I can't get any lower on the front end of my current bike...

Obviously a new bike is required. Of course, there is a possibility depending on your current aerobars, that swapping to different aerobars could allow for a lower pad position (such as one that mounts the pads directly to bar).

Thanks, Jordan. I really liked your write-up too - glad you were able to stick it out.

I understand why your bike was off, but it seemed like overall the pro men's bike times were relatively slower this year. Any ideas why? Seemed like better conditions and less wind than last year -- just the dynamics of the race? Of course "slower" is certainly relative, like the commentators in the Chicago Marathon calling the 2:09 pace "pedestrian" (and that was certainly a case of race dynamics).

I don't know if you've commented on this (or if you want to), but I wondered how your speed/power relationship (i.e. CdA) has changed since you've been on the Dimond. Twelsiek certainly rocked it, for example going 2' faster than FVL on 14 fewer watts (& he's a bigger guy).

I think we can take away 3 things from this data so far:

1. Those Xentis 5 spoke wheels are for shit.
2. The Dimond is a frame which excels in the kind of wind we saw (and usually see) at Kona.
3. Jordan Rapp gets one more point in the BAMF category.

Couple things. FVL runs Q-rings, which artificially inflate power numbers quite a bit. FVL also has, quite honestly, a terrible position. Head way up. Chest open. Straight extensions (WTF?!).

So there's all that.

But overall, power numbers just seemed lower this year compared to last year. I mean, even Maik was about 10w lower than last year. And that looked pretty consistent. EVERYONE seemed to be riding about 10w (or more; Kienle was probably more like 20w less) - which works out to about 3-4min over 180k. I think it was because it was hot and relatively low wind, which made it seem REALLY hot. Last year was windy, but that also meant a lot more convective cooling. So better conditions? I'd actually say no. Low wind, high temps, and high humidity is probably the toughest conditions for hard riding. I think that's why there was such carnage.

I really noticed once I got to Kona just how fast the Dimond is in crosswinds. At home, because of the nature of topography, the breezes off the ocean are all channeled so I ride basically into a straight headwind or with a straight tailwind. The Dimond is faster than the Shiv, but not by much. I can pick it up on routes I ride a lot, but it's not really that much. But in Kona? Holy shit. I was doing race pace intervals and just flying. I did a straight out-and-back at my goal race pace - 292w - before the race and was doing like 44kph on the Queen K section where I did it. So I really noticed the difference in speed on the Queen K way more than I notice it at home. I'd say my 0yaw CdA has dropped a bit. But my 10deg yaw CdA has dropped a LOT.
