The Bank of America Shamrock Shuffle keeps racking up talent.
Race organizers announced this week that U.S. Olympian Lisa Uhl will make her competitive debut at the 34th annual run known among locals as the unofficial kickoff to running season.
"I have always been in love with the energy of Chicago," Uhl said. "Not only am I looking forward to testing my fitness on a fast course, but I am thrilled to be part of such a fun Chicago tradition."
Uhl finished 13th in the 10,000-meter race at the 2012 London Games during her first Olympic appearance. She set a NCAA collegiate record in 2010 with a 10,000-meter time of 31:18.07.
"Coming from neighboring Iowa, she has trained hard throughout the winter and is ready to ring in the spring racing season along with the rest of the Chicago running community," Executive Race Director Carey Pinkowski said.
Uhl joins Olympian Dathan Ritzenhein on the course this year. Ritzenhein returns to Chicago after finishing 13th in the Olympic 10,000-meter final as a member of his third Olympic team. He finished ninth at the Bank of America Chicago Marathon last year.
Danni Allen, winner of the latest season of "The Biggest Loser" also plans to run the Shuffle as part of her training for the Bank of America Chicago Marathon.
The 26-year-old started the televised weight-loss competition at 258 pounds and weighed in at 137 pounds by the end, enough to earn her the title and $250,000.
