22,000 Runners Pound Downtown Streets For Shamrock Shuffle

CHICAGO (CBS) -- You didn't have to run to participate in the 38th annual Bank of America Shamrock Shuffle.

As WBBM's Michele Fiore reports, there were 22,000 runners who pounded the pavement downtown Sunday morning. And thousands of spectators cheered them on.

At age nine, Jaylin Sustr from Bolingbrook was among the youngest runners. Jaylin got the running bug from her mom, Courtney, who ran the Shuffle last year.

"All she kept saying all year, 'I want to run the Shamrock Shuffle!'" Courtney said. "For Christmas I registered her and I for the Shamrock Shuffle, and here we are."

Steven Sambu made it a three-peat, winning for a third year in a row with a time of 22:47. The women's title went to Kim Conley in 25:43.

Sambu, the world's fastest man ever over the 8K distance (22:01.1), is just the second male athlete in the event's history to score the hat trick.

Conley, the 2015 U.S. half-marathon champion and a two-time Olympian, made her racing debut in Chicago, winning by nearly a full minute.
