What's your top speed?

@Hippy.
Just used that Analytic cycling site to do some calculations for a fixed climb that I will be doing soon.

I'll be using 41:23 over 21km to an altitude of 1.5km. I was looking to at least beat 2 hours, but according to http://www.analyticcycling.com/GearSelectionTouring_Page.html I'll need to maintain 200 watts to achive this. Crap question, but does that sound like alot to ask?

How much do you weigh? Are you slightly built or do you look like the side of a shed?

200W isn't much for me (easy cruising speed, say 25kph on the tops in low wind) and shouldn't be an issue for most people that have done any amount of cycling and aren't at the 50kg end of the chicken leg scale.
