Long Run at Ideal Race Pace

Yesterday, I set out to do 8-10 miles at my ideal race pace, and ended up at 8.33 miles (details).  I did it at an average pace of 8:46 per mile, which would put me at a solid 1:55 half-marathon.  If I could do that, I would be ecstatic.  I couldn't have done it yesterday, I know that much.  I was pretty pooped at the end of it.  But again, I hadn't been preparing and eating healthy in the days before, so I think under race conditions it might be doable.  Only one more quality training day left (Tuesday) before the race; the rest will just be easy 30-50 minute runs at around 9:30 pace to recuperate.
