I've had a head cold all week. I ran on Monday, then took the next three days off to rest and recover. Today, the cold is still kicking, but I needed (or felt I needed) to get out for a run, since my half marathon is coming up on Oct. 11th. I had scheduled a 10-mile tempo (or race pace) run for today. I ran my out-and-back course, with the intention of turning around wherever I thought I should (yeah, right). Of course, I got to the five mile mark before turning around. I ended up running the 10 miles in 1:17:41 (7:46/mile pace). I felt much better than I expected, although the last couple of miles were tough. And I wish I had had some tissues out there (I won't go into details, but it was a bit messy, thanks to the head cold). For the first time, I carried my Nathan hand-held water bottle...and I wasn't really loving it. I'm sure it'll take a few more runs to get used to it, but I think I actually prefer my belt. I switched hands every mile, but my arms and hands still got tired.
So...this run built my confidence, which I felt I needed going into the race - especially with this cold. Now I'll put it on "cruise control" from now until the race, doing a few more easy runs before taking the last 3 days (or so) off before the race.
(EDIT: the blisters I got on my 14-mile run a week ago are gone. Taking the last 3 days off due to my cold helped them heal. I ran in my new shoes again today, but used my old inserts...so it was the new inserts, not the new shoes, that caused the blisters. Good to know)
