Power

SteveR_100Milers · June 2007

spent 45 minutes in the gymn (of the hotel im currently forced to stay in against my will) and after an 11 hr flight and about 5 hours rest, was absolutely s****d at about 130 bpm (75% ish / but RPE of 6-7) and 250 watts. This seems pathetically low, which I am putting down to the long flight. What is typical power o/p of someone mid pack TT ability of large build (6ft 1 89kgs). I was expecting to be able to churn out 400W but perhaps this is overoptimistic. Is there a site anywhere with some sort of tables of power o/p, body weight and climbing speed etc??

Time! Time! It's always too long and there's never enough!

400 watts is VERY optimistic and unless you are at very good national level you won't be pushing this out. I push out about 300 watts on a standard road bike for a short 23. There is a site somewhere but can't remember it!

Is this what you want?
I find it a bit more accurate than the Kreuzotter(?) application.

how do you measure the watts?

I work hard because millions on benefits depend on me

Jonathan, I'm not being funny mate but given your size, 300w should be giving you a lot quicker than a short 23. Are these rough ball park figures or have you measured them? I'm asking because I'm intrigued by the way. Seeing you at the two up, I'd have though given your size and age, you'd be putting out less watts for a 23.

Steve. iirc, Boardman put ouw 450w during the hour record, so 400w might be a tad optimistic![:0]

According to the site below, at 70kg, 400w is within the world class range. For a heavier man it would still be pro rider stuff.

I've hunted around for better references since buying a turbo with power output readings and bought a power training book - very little seems to tell you specifically what your values might mean. I weight 72kg and can put out 260w avg for 20 mins. According to this site that's intermediate.

Power - Weight - Position - Duration.
They all play a part in every individual's equation.
I can hold 400w for about 2 minutes before I blow.
250w gets me a mid 22, and a shortish 56.

Thats interesting, not sure about the accuracy but I suppose its an indication. 250 ish watts gives me a 24.5 for a 10 on a flat course, which is pretty much what I have done. I'm going to have a bash at intervals later out of interest to see what max I can generate [:)]

Well it would give me a lot quicker than a short 23 on a lo pro but I just use my road bike. Looking at the power calculator from the link on the thread it shows at 300 watts I would get a mid-long 23 when using the drops. I don't know how accurate it is but can't be too far off.

SteveR_100Milers · June 2007

Dodgy power meter - I managed a peak of 512W for an all out effort standing up on max resistance. I was doing intervals of 1 on 2 off x 6 at 300 ish and it killed me, I was over 10TT pace effort. I would expect to be on the high side because of my size, after all its about power to weight and frontal area/drag, but from the above not 500...[:)]

Cant get the Austin one to work but find the Kreuzotter in the right ballpark.
e.g. I have just done my first ever TTs, both on a standard Roubaix (no tris) riding mainly on the drops.
10 miles avg 325W 23.51 avs 40.3kph (Kreuz =40.6)
25 miles avg 280W 1:03.18 avs 37.9kph (Kreuz = 38.3) (PS this was won in 55 mins by guy who reckoned needed to average 330W).

Wow...please tell me your weight and send us a picture of your position.

300 watts gets me a 23 and a midling 58.

Cheers

No current pix - I'm doing the Bournemouth Jubilee whs event on the P613 on 16/6, and Kimroy are scheduled to be there. I'll let you know if there are any decent profile pix just after.

Not sure how accurate the site is for calculating but according to site for my weight and using drop bars,19lb bike for a dead 24 10tt it says 310w and for fastest time I did 23 years ago on 22lb bike comes out at 390w.
