It's certainly not the first marathon to be run in 80+ degree heat, but it's certainly out of the norm for October in Chicago.
EDIT: Only 30 runners were actually hospitalized, another 200+ were given first aid on-site.
The runner who died, a 35-year-old Michigan police officer, died from a heart condition, not from the heat. But it's still a sad day, and a hell of a poor showing for Chicago. There were reports earlier of runners fighting with police for the right to finish the race.
