I'm not using aerobars, but I've been trying to stay in my drops for the entire time. I have bars, but I've never used them on the road. (I put them on my trainer bike becasue I was having some issues with my hands, and I was experimenting to see if riding was exacerbating the situation.)

I'm also not sure of what my exact LT is. I know approximately though, and I'm hoping to stay slightly above that for as long as possible. Is that a good game plan? I think it's at about 160 bpm, and I'm hoping to ride between 165 - 170 bpm. Max I've ever seen is 179. I might go to 175-177 for the last mile.
