Goals vs. Expectations for Classic Rock

I have been working toward achieving certain goals for Sunday's race. Based on my training times and the course, my expectation is that I won't achieve those goals.  However, I'm not going to lower my goal just to be able to say I hit my goal on race day. I'm still going in with my same goals, still trying to achieve them, even though it's likely I won't.  The course for Kemah was a faster course than Classic Rock, both for the run and the bike it was flat. But the second half of the Classic Rock bike course is full of inclines and a constant headwind. The last 3/4 mile of the run is a long, slow incline as well.  I haven't hit very fast times in training on either of the courses.  The only place I expect to hit my goal is in the pool.
Goals for Classic Rock:
Swim: 6:40
Run: Pace 8:45,27 min
Bike Pace: 17 mph, 42 min         
Add transition times and my goal time to finish the entire race is under 1 hour and 20 minutes. My last race on this course is 1 hour 24 minutes.
