UPDATE 10:40 ET: Sammy Wanjiru of Kenya has won the Bank of America Chicago Marathon in 2 hours, 5 minutes and 5 seconds. This is his second consecutive domination of the 26.2 mile event.
Wanjiru's victory was all the more impressive because he'd been getting over knee problems and had a stomach virus which set back his training, commentators said.
Liliya Shobukhova won for women. The Russian runs an average of about 140 miles a week to train, a commentator said.
While Wanjiru and Shobukhova enjoy all the free bagels they can eat - and monetary prizes - there are about 41,000 runners who are still out on the road. They are facing unusually hot weather with temps reaching into the 80s. Watch them run on CNN.com Live.
