Medium route looks nice. It will be moderate/rollers with the exception of the climb, which I assume is up Cavedale and then down Trinity. Cavedale is not a steep climb, but it is probably 3 - 4 miles long. The pavement stinks, which will be less of an issue for you than if you were descending Cavedale. The Trinity descent should be taken with caution. That road IS steep and twisty.
Have fun!
