Yeah I reckon I've still got a few kg to go. 83-84 kg has been my target and I should get there soon. Hoping the watts keep sneaking up as well !

Yep - but make the bin width 5W/10W and see how those look.

Grrrrr. 192cm, back up to 98kg from 93kg after a slow winter, my FTP was around 390W back in January. Originally 127kg, spent the last few years at 105kg before getting over that plateau, but my body is fighting back ATM.

That's great work to get those pounds off. I was 108 kg two years ago when I started riding again. I had been as high as 115 kg at one point.

I think we can safely say that you did not ride it like a TT.:P

Thanks for putting it in layman terms, I struggle to understand the tech figures.

While understanding its a rough rule of thumb I can look at my NSW ITT result, where I was a massive 6.76 seconds per K off the winner while making the assumption that 1 second = 10W as me at a 67.6W deflict. Anyway whatever the exact figure is, I'm a long way off.

I think that graph just about closes the thread out. Sorry Arthur. Sounds like you pulled a massive coup with 5th place, given your struggles!

Interesting Twizzle, made me go back and look at 2 TTs I have done in the last few weeks, my better TT was a lot more consistent than my bad one. However, still not even nearly consistent as yours though both TTs were quite hilly.

I just realised the "with zeros" option is off by default in this version of GC. So there was ~ 3:30 of "zero" in the first and ~1:40 minutes in the second.
