Chicago Marathon winner Evans Cheruiyot, who made his marathon debut less than a year ago, made it six straight wins for Kenya in the Bank of America Chicago Marathon Sunday. Breaking away from compatriot David Mandago in the 25th mile, Cheruiyot finished in 2 hours, 6 minutes, 25 seconds.
Lidiya Grigoryeva of Russia, 34, the 2007 Boston champion, took command of the women's race in the 21st mile and went on to win the title in 2:27.17. She led another Russian, Alevtina Biktimova, to the finish.
Cheruiyot, 26, now is 2-for-2 since moving up to the marathon a year ago. He won at Milan last December in 2:09.16.
Mandago was second in 2:07:37.
