what gearing are you running? down around 20 kph for 90-seconds doesn't sound "big-ringing it" to me ..

stay aero

I was thinking the same thing. Big ringing hills for 90 seconds at 14 mph sounds like a recipe for some trashed legs. I prefer to keep the cadence up.

I did a very hilly 20 mile TT this past weekend (2,000 feet of cum elevation gain per my Topo software ... which I think tends to exaggerate, but still ...). I like to stay aero as much as possible, but ultimately, you've gotta do what's going to keep you going the fastest. I was out of the saddle, into the small ring ... whatever it took to keep it going.

I think there was a time when the prevailing thought was to stay aero almost no matter what. But watch the top pros like Cancellara nowdays. They use all the bike and do whatever they need to do to get the most speed. Ultimately, that's all that matters.

The "science" on any matter can never be settled until every possible variable is taken into account.

I did the same race as Psycholist Saturday,i like to slide back sit up a little and try to power up the hills,i did stand up parts of some hills,standing gives me a little break uses some different muscles then i sit and get aero again

I just looked at the PT file again to get the numbers right. Gearing is 53 front 12- 25 rear. I was climbing either in 53x23 or 53x21 (or whatever the 2nd and 3rd largest cogs are). 73 seconds to climb the one hill that bothers me most. 390 ave. watts, 81 ave RPM (63 min.) 17.5 ave MPH (12.5 min). Probably going 12- 14 MPH for 10- 15 seconds

I am thinking aero is the way to go, if for no other reason than to keep me from going standing and sprinting over the hill and blowing up. I seem to be able to keep myself under control better if I don't stand......
