CHICAGO -- So forget that negative split storyline. A quick check of the weather and on-course reports shows that this strategy would only be for the insane today.
From the Chicago Tribune:
Unseasonably warm weather sent six high school athletes in Sugar Grove to the hospital Saturday, and officials warn that the heat and humidity Sunday could be even more brutal for the record 45,000 runners expected for the LaSalle Bank Chicago Marathon.
"This is weather more typical of summer," said Andrew Krein, a meteorologist with the National Weather Service in Romeoville. "When they're out there running, they should really treat it like a day in the middle of August or July."
Krein said that the temperature is expected to reach a record 88 degrees downtown Sunday and that temperatures in the 90s "are not out of the question." That would mark the hottest Chicago marathon since 1979, when temperatures hit 84 degrees.
