Hey. I started riding heavy in the spring or so and am very pleased with my progress - especially on hills. I have worked on this and when I ride with my buddies I drop them easily and this weekend in Austin at the Ride for the Roses consistently performed very well on the hills. I have been working on this which was easy (want to get better on the hills, go ride hills. . .). However, I noticed that on long flats I struggle to keep up and seem to be expending a lot of energy. So my question is how do I improve my riding in the flats? High/low cadence? Just ride faster, etc. . .any drills?
