Mission accomplished!
I'm at the airport now, heading home after a long weekend with multiple 2 am wake-up calls (5:30am race starts). After yesterday's "inadvertant race", I went into this morning thinking things were going to be tough out there. After yesterday's run, I also knew that running the tangents is impossible on this course (my Garmin said that I ran 26.5 miles today). So, I went out at about 6:40 pace planning to hold it until the wheels came off.
Well, the wheels never came off. I ended up running a 2:56:14 for a 6:43/ mi pace, with the second half being only 11 seconds slower than the first half.
Thanks for all the comments. They really made me want to hit my splits out there.
