The Chicago Lakeshore Marathon, which is a qualifying race for the Boston and Chicago marathons, gets a long front page article in the Chicago Tribune today for being 1 mile too long. The half-marathon was also too long. (This makes everybody's time longer, and lots of people are close to the time cutoff for these events.)
The woman who was in first place most of the way through the half-marathon got directed off-course and ran an extra mile. She finished third.
Runners throughout the area are calling for the organizer's head. They are not being polite about it, either.
