Cool, let us know how the training goes. You might experiment with going harder on hills and recovering on the flats, vs. maintaining the same effort up and down hills. As far as the physics go, it's more efficient to put slightly more energy into climbs than descents, but some people really favor one approach over the other. I take clients to a 3-mile TT course and have them ride it both ways, alternating, to see which is faster for them. It's surprising how different the times can be. You can also change preference as fitness changes, so it's good to test this every season or so. Really strong time-trialists tend to favor the consistent effort with a very slight bias toward hitting the hills harder.
