ok, here's the caveat: the TT course for cascade was just the out & back ascent/descent, not the loop around the golf course. i understand that has some steep rollers.
i actually ran 53/39+11-23 on the TT bike. i'm a bit of a spinner, and while if i were going all-out for just the TT i probably would have wanted 55T big ring up front. i was still able to spin and put out about 90% FTP on the descent, which was what i wanted to do for pacing. (keep in mind this was part of a stage race for me.)
if you are confident on your TT bike in terms of handling and want to put out max power, you'll want the biggest gear you can run. 39x21 or so was fine for me on the ascent. (my FTP is 4.4w/kg, for what it's worth.) i tend to spin at 90+ while climbing.
it's worth scoping the course. my experience is that you either want to be on the right or left side of the land and not so much in the middle--there's a bit more "pavement weirdness" in the center. however, in the 2 "ruts" where car wheels most often travel, it's pretty good. the course is pretty protected from winds, with the exception of one short area at the bottom.
for the nationals road race, i ran 50/34+11-25, but only because that's what i needed for the other stages. i think you'd be fine with 53/39+12-25. i didn't spin out at 50x11, and i doubt you would at 53x12--butat around 38+ on descents i tend to coast vs push in most circumstances. there are essentially 2 climbs. one is longer but not terribly steep, and the other is sharp but short. if you're looking to do well (which i assume everyone will be aiming for!), you're probably not going to be in the 39x25 on that climb.
the awbrey butte circuit is really cool! make sure you're at the front when you come out of the last roundabout.
does that help?
