CHICAGO (CBS) — Over 40,000 runners from 120 countries and all 50 states came to Chicago. All eyes were on our city for the marathon, while trained eyes tried to keep the city safe.
There were bag searches, bomb sniffing dogs, barricades on top of barricades and police patrolling every inch of the race course.
The 2013 Chicago Marathon, the first major U.S. marathon since the Boston Marathon bombings, and the heightened security was very hard to miss.
Even federal agents from the ATF, FBI, and U.S. Marshal Service stepped in to help.
Runners and their supporters waited in long lines just to get inside Grant Park through one of four security checkpoints.
