I ran a "beer half mile" tonight since I measured and marked the course today for the beer mile. I ran fairly hard (in my street clothes), but I drank Yazoo Pale Ale from bottles, so that slowed me way down. On race day, I'll use Coors cans.
This also allowed me to test the course. Afterward, I trimmed a few more places where the shrubs overhung the course too much and might interfere with faster runners. I'm looking forward to race day!
