The 2013 BTN B1G 10K was held Saturday morning in Chicago. It was the second annual running, and a record 11,415 runners finished. See some of the best photos from the event in this post. There were a couple surprise visitors at the event, too, as Testudo, Maryland’s mascot, and Scarlet Knight, Rutgers’ mascot, were in town for the fun. Both schools join the Big Ten in 2014.
