"I just tried to set a pretty decent pace and drop them," Smith said. "The first 10K was pretty fast."
Together through 10 kilometers in 31:48.7, it appeared Smith and Kiros would race neck-and-neck through the final half of the contest. But moments later, Smith put any thoughts of a duel to rest. Pumping her arms ferociously, the three-time Olympian eased away from Kiros. A five second lead soon became ten seconds, then 30 seconds.
"Once they dropped off I knew they must be tired, and I felt pretty good at that stage. I thought 'I think I got it,'" Smith said.
All by herself, Smith continued to push over the latter stages of the race, through Franklin Park Zoo and into White Stadium with no woman in sight. By then it was clear the previous course record of 1:10:52 would be beaten. The only question was by how much.
The answer wound up being one minute and 38 seconds, as Smith broke the tape with 1:09:14 reading on the clock. Though she easily secured the course record, Smith said it was never on her mind.
"I knew I was running pretty fast going through 10K. I didn't really worry about course records. I just wanted to win," she said. "I was just running and felt pretty good."
Smith's next race will be the New York Marathon on 3 November.
