The 2012 Chicago Marathon in photos
The Chicago Marathon is a magical day for street photographers. 45,000 people running through the streets involved in dramatic struggle, yet completely unguarded in their facial expression- it's like Christmas for shutterbugs.
Yesterday's event was no exception. WBEZ's Flickr group members got some great shots as you can see in the slideshow above. To add your photos to this slideshow, submit them to the WBEZ Flickr pool with the tag "chimarathon2012."
