That analysis wasn't particularly insightful.

How does w/kg on the bike leg give you more insight into potential run performance than something like, say IF? In other words, % of FTP?

Because light people run fast?

Light people with relatively large motors run fast....light people with not great motors (relative to weight) but with good CDA may bike fast but still run slow.

Of course, that's just physics...but, I still don't understand how looking at W/kg alone on the bike leg is going to tell you this...especially in the context of triathlon and looking at how well it was raced.

Correct, looking at Watts per kilo in isolation would not tell the entire thing...as you said looking at %FTP along with watts per kilo will give us a better picture....then of course we have to know their run Vdot and run mileage in training to get the bulk of the rest of the picture. Would be interesting to know Jordan and Clayton's current Vdot's.

None of this takes into account how effective their fueling was. Once you get into small percentages of performance differences, how smart they fueled can make a huge difference in race results between competitors. Incomplete picture for sure.

Right, but I thought the point of the analysis was to look at how they did within the context of their own potential, not necessarily their overall potentials.

BTW, if Fettel hadn't gained the extra 8kg, he and Jordan would have had nearly the same W/kg average output on the bike (they averaged nearly the same power and both would have weighed ~70kg)...seeing as how he has a "bigger engine" (as evidenced by his higher FTP), does that mean he would've run faster than Jordan?

Unless something has changed, I believe Eneko Llanos, the winner, does not race with a power meter.

Edit: Run 2:43. SICK!

So.... what conclusions can we draw from that?

The watts per kilo and percent FTP would give us an insight into run potential...but their Vdots will also be limited by some biomechanical considerations. Two guys can have identical engines but one guy can be a lot better runner because of things like bone geometry, tendon lengths etc. That should show up in the Vdot number.

none. that's not the point. the point is, when someone DOES ride with power, we can look at the data and learn some things from them.

what we are NOT learning is, "oh, so and so did this, so we should do the same and copy".

Right. Continue on with analysis of 4th and 12th place.

I'm kidding in the sense that their computer reported vastly different amounts of climbing. I'm assuming the amount of climbing is used in calculations for things like IF and TSS, so comparing them is difficult in this case.

I would love to analyze Eneko too.

Will start as soon as he races with a power meter =)

Or, if we want to argue from authority (http://en.wikipedia.org/...ent_from_authority):

Wiggins, Boardman, Craig Alexander

Ohh!
No, climbing is not part of IF/TSS at all.
Only power and the athlete's FTP

isn't he creating a strawman?

Yes, I am. My bad. Eneko is irrelevant to this thread.

I'll start a thread titled "How can Eneko possibly run so fast without a powermeter? Impossible!"

Obviously he is biking too slow!

Fettell wins. His SWEET socks and rockin' mirror visor convinced me.

He does dominate Jordan in the "socks I should have stopped wearing in the third grade" department.

How dare you sarcastically make fun of that visor though ;)

In terms of equipment selection based on racers' strengths, a guy who expects to be first out of the water and leading some or potentially all of the bike comes prepared to monitor his numbers.

A guy who is pretty sure he's going to be chasing from behind after the swim and riding solo/driving a train sees the benefit comes prepared to monitor his numbers.

A guy who knows he can swim first pack and is one of the fastest runners in the field and intends to ride with the lead pack for the whole bike ride maybe doesn't feel like he needs to be glued to a powermeter, just in the flow with the lead guys?

I have no idea how they are calculated but if two guys do a 60 minute 40 km ride, one dead flat and one up a 5% grade. Assuming both are the same weight and same FTP wouldn't ones IF and TSS be higher?

Same way all the XC skiers can ski so fast without any data staring them in the face. Good athletes are highly tuned into perceived exertion and energy expenditure. I bet Rapp would race the exact same way off "feel" if his power meter conked out.
