Record-setting temperatures in Chicago on Sunday brought the 30th LaSalle Bank Chicago Marathon to a close prematurely after one runner collapsed and died, and 302 others were taken to the hospital to be treated for conditions related to the heat.
It was the hottest in the marathon's history, hitting 88ºF/31ºC. Of the 24,931 that participated, 4,000 finished before it was shut down at 11:30 am, 3.5 hours after it started. Firefighters hosed down runners and made an announcement over a PA.
Runners who crossed the halfway point when the decision to stop due to slow finishing times were allowed to finish. One runner, a teacher of 70, said she didn't like dropping out but knew "when to take a recess," running in 17 marathons since age 60.
