I feel bad for not mentioning sooner this run, which is prolly one of the best-kept secrets in the city, the Epidemic Intelligence Service Prediction Run.
The CDC's "disease detectives" holds the run each year as part of their scientific conference. It's a 2-mile run in which the winner is the one who most closely predicts his or her time without using a watch.
It's at Piedmont Park on Tuesday (6 p.m.). And the T-shirts are pretty frickin' cool.
