Very interesting for anyone who is interested in "seeing" how hard it is to ride in an ITU pack.

Not huge numbers but then one has to remember that Matt is a pretty small guy. Looks like they were riding in a bike race or something, who knew. ;p

Matt is a stud on the bike! They need more hilly courses for these guys.

Cool data thanks.

 

I'm actually UNDERwhelmed by that wattage data. 300 watts for an hour is no joke, but there are actually a fair number of age groupers who can do that on a bike.

 

Now running a 31:00 10k after the hard bike - that's something pretty much zero age groupers can do. I was expecting to see a bike power output well out of the range of age groupers - maybe he's extremely light so he's got an unreal power/weight ratio (altough it would probably be more power/CdA on a flat course?)

It's harder to avg 300 watts when going up and down constantly than going out and just riding right at 300 watts. I'm on the smaller/skinnier side at 5'10" and 147 and Matt is probably 3 inches shorter and 15lbs lighter... so that's very good power to weight ratio to say the least. Also, if it was a hillier course I bet his power would be higher.

?at 62.6 kg, or 139 lbs?

no, there are not a fair amount of AGers who can do that. 

also, review the file.  it's the surges, not the AVG that matters.....go bike for 300 watts for 30 mins, then go as hard as you can for 30 seconds, then continue on at 300 watts. 

also, you dont know when those surges are coming.....and if you can't surge...BYE BYE--you just got spat out the back

I'm his size, those numbers are only something I dream about.

Could not agree more about the hills, this past weekend everyone in my tri club was yelling, "Brian, hill" on our group ride. And then there was the flats, and the joke wasn't nearly as funny.

I can think of one in my area(chicago land) that is close to 138 lb that can push close to 300 watts for an hour but it would have to be a steady state. The accelerations to 700 watts would pop age groups right out the back of the group and no way could they bridge back up. The significant of those accelerations is very taxing on the body and doesn't show up in average number or really even NP.

I have a lot of crit data that shows my ending ride at an IF of less than 85% which I can do for hours in steady riding, but I'm shelled due to the constant accelerating and trying to hold wheels out of turns.

I think from the above is what will make Skiba's W Prime work interesting to follow...

.

W/kg were 4.4, which is pretty decent considering the subsequent 10k. Actual average was 275, and he weighs 138lbs.

its beyond decent.

what makes the file WORLD CLASS is the surges at 500 and 600 watts after riding for 290+ for 30 minutes....

As has already been pointed out---it's the power-to-weight ration AND the surges--unlike say a HIM or IM where you have steady state power---check out his VI of 1.25---that's not "by choice" but dictated by racing---those surges would "pop" (like Fred being subtle---perhaps EXPLODE would be more appropriate!) most...

Edit:  Hmmmm the 1.25 was when I was looking at the "full" activity on TP but it looks like from the ST graphic that the 1hr VI was more like 1.09 so not as "punchy"....

Fred D - 2012-05-14 11:30 AM Sidebar, there was another runner who ran a mid 31' 10k. He didn't finish that high, but some might recognize his name.... Chris McCormack. I bet some ironman pros are freaking out about that little stat as Chris will probably race Kona this year.

Yeah I've seen a bunch of pics of Chrabot and McCormack running "together."    It will be very interesting to see the speed translation to Kona...

Some will also recognize Hunter Kemper who's still killing it out there.  He took 5th and will be going to the Olympics for the 4th time for the USA.

I so need to get a power meter.  Not that I'm anywhere near these levels, but I'd just like to compare and better watch my progress.

x2 the shout-out to Hunter Kemper. I saw him crash hard in SC and taken off the course in an ambulance. It is great to see back and racing hard.

. Oh I agree, I was trying subtly to refute any claim that it wasn't special. His NP w/kg was 4.8, which is also 'ok'

From a pure cycling perspective it is not world class. Looking at the power file his IF is .95 for the effort with a NP of 301, this puts his FTP around 316.84. Using his 62.6kg weight puts his FTP at 5.06 w/kg. Comparing against the Coggen chart (2006) this would put his ftp in the middle Cat 1. The hardest effort of 700+ (11.2 w/kg) for 10 seconds was at the very end of the ride.. the minute before his AP was 214, NP 222 (a 70% effort) .. 11.2 w/kg for 1 minute is world class, 10 seconds is just a hard neuromuscular surge.

Nice ride, but I would have a hard time justifying it as world class versus pure cyclists. World class for triathletes, I don't have to a stick to truly measure against but I know pros that weigh in the 150's will hold around 300 watts (AP) at kona.

It's an ITU race, so the goal is to put out the MINIMUM wattage needed to enter T2 in contention (ex. he shut down a bit once it was clear the break wasn't going).  Matt's one of the stronger cyclists on the circuit; as he's mentioned in some interviews, it's the surges that kill ya.

16-17 min or so for a 1500m swim and 31 min or so for a 10k is hardly world class either. Let's just just forget about these guys completely, they have no clue what they're doing.  Wow.

There are very few AGers who would be able to hang on to that group on the bike. Even for athletes who have a high FTP, triathletes typically are ill equipped for the demands of bike racing and would be spit out the back after the lap (at the latest). The key to seeing how hard this ride was isn't the AP or NP but rather spikes that are >150% of FTP - the typical triathlete does not train for nor are they prepared to spike their power like that for as long as required to stay with the group and then to "recover" in high L3/low L4.

And that's before factoring in Matt's size, or lack of. ~138 lbs really isn't much for a guy.

Well since this is evolving more into a general ITU bike discussion---it's been mentioned that Macca is in fast run shape due to this ITU "stuff."  So the question for this thread is how does this "change" in bike training/racing translate to long distance (Kona) for him??  Since he's used to the surging of ITU he can certainly cover a "lifting of pace" at Kona but does that help him??
