Since I'm guessing you're all like me and find the threads that are all about me the most entertaining on this site (like who wouldn't!).

 

So, I thought I'd throw this out there.

 

I did a PB ftp test the other day. First time I've ever done one well rested.

 

As I have been called for BS on this in the past and I know at trannies get together you can talk of little else than my ftp, here 'tis: http://perfprostudio.com/users/MJ8TCQA/20140904/pkdtmn/pkdtmn.htm

 

Still only second on the leaderboard as the lame-asses still rank only as per kg, because just like the Tour De France, in triafalons the only time that power you can produce matters in the weeks of racing is those 3-4 x 30minute efforts up a mountain.

nice effort, seems you really left a lot in the tank in order to push the final 5 minutes so hard?

 

Although I would have to say your comments re: the leaderboard are a little odd. They have both w/kg and watts leaderboards...

It was obviously done on an indoor trainer.

To have an avg power of 373 watts with an avg speed of 33kph means either you were doing the test on an uphill segment, and/or the data is "virtual" data... ie not from an actual power meter (rendering it pretty useless for comparison - only good for you to use to train to on the same trainer)

I can see the 20 minute "test", but what does the rest of the session look like. The one I have done on Trainerroad goes for a full hour with the 20 minute test between the 35 and 55 minute mark, with a couple of short over ftp intervals before hand.

 

What else does this test involve or is it a straight 20 minutes only?

I'm going to guess he did the standard athlete lab warmup - this is what that looks like: http://perfprostudio.com/users/QNAVKV8/20140708/4xhwbn/4xhwbn.htm

Can someone tell me how to do this test?

 

Go out on your bike.

Warm-up, include some 105% short efforts (1min or so).

Go as hard as you can for 20mins.

95% of the Average watts for that 20 mins is your FTP. Though I think it is more like 92%.

 

There is only 1 way to know what your FTP really is.

Nice. How many years has it taken you to get these numbers?

 

8 years in tris 6 years of Ironmans, a lifetime of being awesome.

looks about right to me....what sort of power meter.

 

Computrainer

How tall are you?

Nice test.

Watts/kg might not be a huge issue in busso or many tri courses vs raw power but there is still the run afterwards

1.88

 

I know only too well about that unfortunate run atferwards. :shy:

 

I predict your real FTP is probably more like 340-345.

 

A 20 minute test might look good on paper but FTP is 1h hour best effort, if you want to know what it really is, try it and see.

 

Keep it real...

 

Agree. But there is always variablity with the numbers, depending on a range of factors, which is why I find it a bit hard to believe runnng at exactly 72.5% of your ftp is the key to a succeful IM run.

 

I don't think I could hold 354 for an hour on the flats in the aero bars. But if it was on a climb for an hour I'd go close I reckon.

Yeah the guy is in your ear the whole time telling you to pace it, and keeping you focused. It's much easier than doing it on a home trainer or by yourself on a flat strip of road.

At the Athlete Lab in Singapore they only record ftp/kg, no mention of total watts. I guess in Sydney/London they put total watts as well? I told them they should and they said women wouldn't want for people to be able to work out their weight.....

 

Regular readers prob know this is a bit of a soap box topic of mine as total power is far more revelant in tris than /kg. The /kg thing is crucial to winning climbs and that's about it. But because winning grand tours is all about those 3-4 climbs we buy into the /kg thing being the most revelant measure. Anyway have been over all this before, and I am obv biased in that I'm massive.

thats about normal from what I've seen of a lot FOP age group IM'ers

about the 4.5w/kg mark

 

however there are still plenty of good AG guys who struggle to hit 4w/kg who can outride most in a 180km (particuarly good swimmers "hiding" in the big fields we have now- they often claim its their "aerodynamics":-))

 

not many people placing in AG with FTP under that

 

nearly anyone with ordinary genes who committs to regular trainer work can hit those numbers

 

now......5.5w/kg+ is a whole different story---you need the right parents for that one

What do you reckon the top tri cyclists that are built like me like Andrew Starkowicz or Tjorborn Sindballe (at his best) would be at?

 

Must be 400? I saw Sindballe averaged 300 watts in Kona when he broke the bike course record.

McKenzie was 281AP 295 NP at kona last year FWIW

I think that was 78% FTP so can do the math there

i think the best triathletes aren't much more than 5.5w/kg

 

then there is a big gulf between them and the 6.5w+/kg tour guys

 

i know most of the younger QAS people test somewhere in the 5-5.5 range

 

.....and then magically top level tour guys emerge 5-10yrs later cranking out 6-6.5......

 

Lance and Tyler almost touched 7w (give or take a bit of propaganda and temporary starvation/dehydration)

 

 

Sinbale probably had a FTP similar to McKenzie I would guess. He mostly raced around 78-80 kg so 8-10% heavier than Luke but its argueable that he always did the bike leg at a higher % of FTP (hes a slower swimmer than Luke, he mostly rode by himself off the front and before the larger packs we've had in recent years)....also judging by the relative way they both executed the run

 

McKenzie clearly had hit a stellar bike ability last year and despite his fast bike executed his run very very well- thus my case to support he might have a similar FTP despite smaller body weight

The under 23 QAS riders aren't hitting 5w/kg....even our QTRS riders are in the 4.7-5wkg range....at 5.5 you would be doing pretty damn we'll

What's even more relevant than power is W/m^2. (i.e. ratio of power to coefficient of drag area). That is primarily what determines speed on flatter terrain.

 

I demonstrated this again recently when analysing Jens Voigt's hour record ride, and how it could have been plausibly achieved with a power output ranging anywhere from 350W to 450W.

Agree, I know of some smaller guys with watts/kg of under 4, but they can still ride very well, even solo, and I put that down to a efficient position, small shoulders and head.

I think for someone like Niseko, being an IM athlete, looking at those test results, his primary concern is fuel....How is he going to fuel an 84kg body for over 9hrs in an IM?

 

He has good numbers, but it will come at a cost on the run.

 

In saying that his results, show that he is pushing that right to the limit.

Wow nice numbers.

 

Can someone explain how the average speed is an average commute though?

 

At 370watts surely would be moving much quicker? Or is this due to the resistance of different trainers?

 

The test used would be on a Computrainer simulating a constant slight/moderate positive gradient. While not perfect, it does a reasonable job of getting the speed-power relationship right, provided the software has been fed the correct parameters (rider/bike mass, simulated air resistance value). This all assumes correct roll down calibration was performed and the unit is functioning correctly.

Ah thanks. Didn't realise there was so much to it.

Exactly!

 

I never get tired of explaining exactly this to every stranger who sees my tri bike when it is outside a shop or the like - "Nice bike mate must be light *picks up bike*, how much does it weigh"?

 

"Well you see it's a time trial bike which means.......".

 

They are always fascinated.

so your saying I shouldn't really consider having a crack with my 270ish ?

Crushed!

The mid 6 numbers are twenty minute climb numbers not flat hour TT numbers.

So take 5% off to start with then take 8-9% off for EPO.

 

What do you run for 10k/ half marathon? If your run gets closer to your bike level then not many age groupers are going to ever run you down.

Sadly there's always someone who comes along and states what the real limitation is - a lot of good cyclists get run down in the marathon :shy: and the guys running them down usually weigh more like Ironpo or Ruley :scared:

Wouldn't say 'guys running them down USUALLY weigh more'

 

Good heavy runners are more an exception than a norm.

 

Note: Said by a fat boy who can't run.
