I ride a very short (~1.5mi) commute to school, with usually 1-3 round trips daily. About half a mile of that is across a bridge (http://www.strava.com/segments/harva...thbound-690537), where there are often fairly strong headwinds. Even in that short a distance, I find the wind really frustrating - as it seems most people do. It seems like I should be riding in the drops, but I can't generate enough leg power to support enough of my weight to feel comfortable - I get out of breath really quickly, and either way I don't like being sweaty on the other end.
Is this an issue of bike fit? In (basically) every other situation, I'm pretty happy with the geometry. My drops are below my saddle, but not by much. Or do I just need to be in better shape?
I have a 2004 Trek 1000 road bike with 23mm tires.
