Chicago marathon ups security after Boston bombings
CHICAGO, Illinois (AFP) - Chicago Marathon organisers and city officials on Thursday announced new procedures designed to improve security in the wake of the deadly Boston Marathon bombings in April.
The race on Oct 13 will mark the first major marathon in a United States (US) city since two bombs went off near the finish line of the Boston Marathon, killing three people and injuring more than 200.
The Chicago event draws some 45,000 participants and 1.7 million spectators annually.
Starting this year, all registered runners must pick up their own participant packets, which include their event-issued bib numbers and other race-related and promotional material. In past years, individuals could pick up packets on behalf of others.
