What was your power during those TTs? I would imagine it must of been much higher than 250, more like 350+

but then again, don't all you Brits do your TTs with 18wheelers constantly passing you?

I have no idea I have only had a powertap since Christmas

I normally arrange 20 Eddie Stobbart's to come by when I'm TTing. http://www.eddiestobart.co.uk/

Ok I'll jump in...


Max power achieved for 20 min = about 330 watts
So FTP as 95% (correct me if I'm wrong) of 330 = 313 watts
18 y.o.
female
have been training but not racing... yet

that still puts you in the 4.4 watts/kG range, still very strong, Cat 1 range as listed in Andys maximal power output table.
wow!

Somehow, I feel scepticism...


Well, I based my calculations on a friend's powertap: we weigh the same and own the same rollers. So with the same tire pressure, this should be the power output associated with the speed displayed. I verified the results with a home stationary bicycle that does display power and the results are at +/- 5 watts difference.

What device are you using to measure your power?

You mean on the stationary bicycle?

Well, there is a simple chart with power numbers associated with the different levels of resistance and rpm.

You really need an SRM, Powertap, or Ergomo to get any accurate measure of power. There is very little validity with wattage numbers from any thing else outside of a exercise lab.

Very well then... Soon enough I will get back on the road (gotta love those long Canadian winter). First thing when I hit the road, I plan to do a little TT to track my improvement. I'll let you know...

Well I've read this thread from beginning to end, so I'll just slink away into a corner somewhere and come back when I have a figure worth posting.

BTW RD (similar age to your's truly)your FT of 325W was last May's figure - what the hell is it now?!?!
