Weekend workout/tempo

I got to Richland Saturday afternoon, still sleep deprived and after a 5 hour drive. I decided to get out for 4 miles to shake the cobwebs off of my legs and threw in some pickups on that run. It didn't feel horrible, but wasn't great either.
I really didn't want to get out of bed on Sunday morning, but I forced myself to do it and I knew that if I was going to get in a decent workout that I'd have to have someone to run with. I ate a piece of toast with butter and jam, a couple of swigs of Vitamin water and about half of a can of flat Pepsi from the night before.
I ran an easy one mile warm up and stretched out and felt surprisingly OK. My original plan was to run the first 20 miles of the race (Tri Cities Marathon) and then bag it. My head cold that I'd caught earlier in the week and the lack of a ride back to my car made me revise my plan.
It was a clear cool morning, perfect for running. When the gun went off I assessed the situation and found the guy who was leading the marathon (there was one marathon relay team ahead of us) and started talking to him. His name was Dan, he was from Portland and his goal was to run 'fast enough to win'. We talked a bit for the next few miles and we were clicking off miles at 6:07 to 6:08 (about 2:41 pace)with remarkable consistency. I decided at about the 5 mile marker that I would go to 7 miles and then jog back to the car, giving me a 15 mile day. Dan and I hit 7 miles in 42:55 (6:08 pace) and I ran back to the car at between 6:40-7:00 pace. My half marathon split according to the Garmin was 1:25:33 and I felt pretty decent about that.
I didn't have any problems with my breathing or anything else because of the head cold, and that surprised me a bit. I am still waking up stuffed up every day and am coughing up nasty gunk, but am feeling better than it was.
I am planning on running an easy 6 miles before the Zeitgeist race and then running the course as a tempo run, hopefully around 6:15 pace. Only 5 1/2 weeks to Memphis !
