The 36th Chicago Marathon kicks off in Grant Park Sunday morning.
With the starting gun just minutes away, runners, officials and spectators are converging for what could be a historic Chicago Marathon.
At 5 a.m., a few dozen security guards from Monterrey Security began checking people into the Marathon grounds along the Jackson Boulevard bridge, just east of the course along Columbus Drive.
The guards searched bags at several tables set up in the middle of the bridge. A large sign affixed to the checkpoint detailed a list of items forbidden on the Marathon grounds:
*suitcases and rolling bags
*costumes covering the face or any non-formfitting bulky outfits extending beyond the perimeter if the body
*props and non-running equipment
*pets/animals (except for service animals)
A few dozen volunteers were already scattered along Columbus between the start and finish lines, and about 40 uniformed Chicago police officers also walked around sporting neon yellow vests.
