Liliya Shobukhova became the first woman to win the Chicago Marathon three years in a row on Sunday.
She finished the 42-kilometer course in 2:18:20, almost four minutes ahead of her closest competitor, Ethiopia's Ejegayehu Dibaba.
"I'm overwhelmed right now," Shobukhova said, The Associated Press reported. "You're happy. You're excited. You're shocked."
Shobukhova and the winner of the men's race, Moses Mosop of Kenya, were awarded $100,000 prizes, and Shobukhova won an extra $40,000 for finishing under 2:20.
Paula Radcliffe holds the women's course record of 2:17:18. The men's course record, which Mosop set on Sunday, is 2:05:37.
