Haven’t seen much data on the power of the ITU guys, but Laurent Vidal posted a picture of his file from New Plymouth, where finished 10th:

Looks pretty solid - 344 avg, 367 NP and some pretty big spikes with the pack riding, for a 66 kg (~145 lb) guy, so ~ 5.2 w/kg. Seems like some pretty hard riding. (Don’t know what’s up with the 311 max avg for 20 min though - maybe a zeroing problem?)
Seems like a lot of watts for a guy his size. That’s almost pro tour level? Or am I totally off…

it is a 26 minute period of time, so either a short course or only a hard portion of the 40k.
If he could do that NP for an hour at his size, that would be approaching pro cyclist numbers. approaching.
I’m guessing it doesn’t include 0s.
Assuming the calorie amount is correct, he burned 529 calories over 28.5 minutes, which is 18.56 cal/minute. Or, 1113 calories burned per hour.
100 W = 360 calories burned per hour (this is a generally accepted number).
So, he did 309 W for the 28.5 minutes (1113/360*100). NP would still likely be 20W above that, though.
This brings AP to approximately 4.75 W/KG and NP to 5.07 W/KG.
Whoops. I thought that was for an hour.
New Plymouth was a sprint I think, so that’s right in line with the distance. Seems like for just under 20K though, for the watts, his size, and the time, something is off… even if he spent the entirety of the race in the wind and not in the pack.
It was a surprisingly tough course with it being quite technical and narrow in places. I saw the file of one of the of the younger guys who raced and his NP of 351w and he is around 67kg. For the guys who didn’t have to chase on after the swim it was a pretty easy ride from what I’ve heard.
That number is definitely off.
Josh Amberger has posted some of his data files on his blog, he weighs around 65kgs and puts out 300-310w/avg for a non-draft OD bike course, and he is a monster on the bike.
A few of the people who raced Devonport Oceania Championships posted their data, averaged in the mid/high 200s with NP nearer 300. Hilly and technical 3 lap course.
The reality though is ITU guys CAN ride!! Especailly at WTS level. The TV coverage doesn’t do the bike leg any justice
Someone else put out less watts for a non draft, longer course, and thus THIS guys’ power file is off?
what?
The fact that peak 20 minute AP is less than 26.5 minute AP does not imply that data is off either.
And while zeros may not be included in the AP listed in that screen, they are in the NP.
I’m going to boldly suggest, that the power numbers are NOT off.
=)

Agreed jackmott, I train with a few of those guys up in leeds and can assure you, those power numbers are not off.
I counted about 35 times he had to accelerate well above 600W coming out of corners, attack or counter. 10 times @ 800Watts, and 3 times at 900W. Looks like a Sufferfest video from hell as there’s no real steady state efforts more than a minute or two. Of course it’s also a 20k. I’d even suggest that it was a harder effort than normalized power gives it credit for, considering that the athlete swam at redline before hand and had to lay down a sub 15’ 5k afterwards.
Here’s my ride from this race on Strava (I’m missing the first minute or so out of transition): http://www.strava.com/activities/123104151 (link to results/splits if you are interested as well: http://www.triathlon.org/results/result/2014_new_plymouth_itu_triathlon_world_cup/264274) FYI, I weigh about 67 kg.
For reference, I was in the back third of the swim, 17" behind Vidal. I was in a chase pack rotating turns at the front with four or five other guys. We caught the lead bunch just after two laps (out of four) at 16 minutes in. I was ~325W for that first 16 minutes and then ~250W for the rest of the ride. Vidal only out split me on the run by 5", but finished 15" or 8 places ahead of me. The difference was likely his positioning coming into T2 (lots of downhill and turns).

Consistent with the data Chrabot released to ST a while back, it seems, though Chrabot’s numbers were for a proper Oly distance WTS.
It’s crazy how hard these guys work. Anyone writing off the draft-legal bike segment at that level as soft is uninformed.
Some dudes need to get off their high horses!
Some muppets show so much ignorance to the absolute elite of the sport.
JP, damn fine bounce back in New Plymouth after the 1st 2 ITU races this season. You showed some guts, and are one of the real classy guys on the circuit. You’ve got a lot of people hoping you do well!! Keep it up.
It is about time that long course triathletes understand what level ITU racers are on. If ITU was easy, more people would have tried.
Racing 1-2 hours is still an endurance sport

Thank goodness you write sense. Sick of reading the assumptions the ITU bike is easy, and the criticisms in general.
Maybe if they all wore compression socks, had an aero bottle, moaned about their nutrition issues, judged each other by how they look and thought massive crowds were anything above 20 people, they would get a bit more love.
