Chicago marathon runners sign up at a record pace

Except for charity runners, registration for the 2010 Bank of America Chicago Marathon closed Tuesday after 45,000 participants signed up in record time.

The capacity was met in 51 days, closing a full month ahead of 2009's record. A limited number of entries remain available through affiliated charities and tour groups for the October 10 race.

"The enthusiasm displayed for this race from runners around the world is one of the primary reasons we are so pleased to continue leading this 33-year tradition," said Bank of America Chicago and Illinois Market President Tim Maloney.

More than 85 of the race's affiliated charities have entries remaining for participants still looking for a way into this year's field. By registering through a charity, runners simultaneously become members of a fundraising effort that annually generates $10 million for more than 120 charitable causes.

"This record rate of registration illustrates the growing popularity of the sport and our race in particular based on our 33-year tradition, but we are also hearing excitement for the historic date of 10/10/10, which adds a unique thrill this year," said Executive Race Director Carey Pinkowski. "The demand that remains to get into this race will be a tremendous benefit to our charity partners and has the capacity to break our record of $10 million dollars in total funds raised."
