What are you all using to measure your power? Hubs or cranks? If this is discussed elsewhere, would be grateful for a link

Have a poke about the TT forums and speak to the guys in the top ten etc ( i train with them )
If you can output 390 watts 20mins ( around 75kg ) it gives you around a 68 Vo2 or 2.20 ish marathon times.
VO2max = 12 * PTW + 3.3

To give you an idea how fit you need to be to push a 350 FTP.
SKR - ex runner and 70 + Vo2
Having the power/tools is one thing, having the mental strength to push to those limits is another thing all together and 90% of whats needed. You can't train for that.
Nice equations. If you can output 390 watts 20mins ( around 75kg ) it gives you around a 68 Vo2 or 2.20 ish marathon times.

I'll let someone who specialises in power do the hard work. Input your variables and you can see what a 350 FTP would 'score' you in a '25'. For me on a full TT rig it would be about 52 mins. Which would put me well outside of the top 200 times this year!
I stick with my assertion that 350 FTP is no where near top 10 material.
Maybe you could post up your power data and times to aid the discussion?

popped into BW cycles in Bristol on Saturadya (new place on Cumberland Basin co-owned by Oli Beckinsale) and they gave nme a bit of a tour as it had only been open an hour or so! they have a full fitting jig and some very scientific looking equipmnent to measure Vo2, fat burning thresholds and wattage etc so I'll book myself in over the winter and see what huge power my feeble legs can generate.
they also stock Cippolini bikes....

So on your link a 75kg rider needs 491 watts using Optimised Aero Bars to ride a 10 TT @ 20 mins.
Lots of guys doing 20 min on 300 watts, on 350 watts 18-20 etc.
In the real world like
Sooo... to finish off, 350FTP ( hour power ) gives you around 390 watts for 20 mins so V fast.
But as you can see not many ( if any ) are knocking out 390 watts for a 10.
And regards me, i can push 380 watts for 5 mins but i've only been training on a bike for 12 months ( was a runner ) told takes 3 years to peak so after this winter maybe 20% gain?, 360 watts for 20 mins and in year 3 ( 10-15% gain ) 400 watts for 20 mins etc and an FTP of 350-370 maybe . I'll come back and tell you how it went March 2013.

Its so interesting seeing the different riders in your category, and how wildly they differ, the issue he will have is that he is racing against people with a LOT more power than him, and most of the races are not going to make the most of his power/weight ratio.
Although interesting that he was only 16th in that iTeam race, I was 2nd in that and it was a flat sprint which he should have done well with with that short term power.

Will Pratt who rides for us is getting a power meter soon, will be interesting to see his figures as he has had some excellent results this year.Although interesting that he was only 16th in that iTeam race, I was 2nd in that and it was a flat sprint which he should have done well with with that short term power.

If it's of any interest to any of you guys one of our 2nd Cat's has posted up some of his data on our club forum if I remember correctly he weighs 64/65KG:
5 sec 1217w
1 min 608w
5 min 340w
20 min 292w
I assume these figures were from one race or training spin and are not all out tests for those durations. If they are all out test I'd be very surprised that the guy is a Cat 2 rider. 5 sec 1217w
1 min 608w
5 min 340w
20 min 292w
Power to weight isn't really signifficant on the flat, so while his 5 sec power is decent (if he still has it at the end of a race) but his low 1 min power suggest that in the final mile of a race he will burn through his reserves before getting to a sprint (unless he has a lead out train) Basically... i'd be surprised that a Cat 2 rider could have power figures that low.
He is a 2nd cat rider, but yes some of the longer duration figs are at the lower end.
You are looking at that wrong chart again skr, look at Coggans, his 1 min is cat 2 level on that chart. I've never done an all out minute but find 30 sec is normally a good duration to have a kick for (1000 for me the other day) as its longer than a lot of people can sustain big power. So someone like the above would have to go pretty close to the line to be in with a shot.

As his results evidence. He seems to have spent his year riding crits and getting nothing out of them. Are we sure he's only 64kg? I only ask as it's a bit odd for a little guy to spend his time riding crits, and if he was a lot heavier then obviously his power numbers don't look as good.

I still think that his numbers (at 64kg) make him look a decent rider with a decent kick, but his results suggest otherwise. Which perhaps goes to prove the old adage that numbers aren't everything (on the road).

Either you guys are tired/mad or cant read

Am I reading that wrong? I'm seeing 9.5W/kg as a mid to upper level 1st cat. International Rider - 9.5 for one mine

Lots at Hog Hill though, which should suit a light guy with a decent 1 minute given the finish.I still think that his numbers (at 64kg) make him look a decent rider with a decent kick, but his results suggest otherwise.

And w/kg doesn't matter a damn when there is a flat finish, power trumps weight on the flat.
