Regular registration for the Chicago Marathon has ended -- and in record time.
The maximum 45,000 participants signed up for the annual 26.2-mile run in just 31 days, three weeks faster than last year.
Marathon representatives announced another record Thursday: $12 million raised by runners during the 2010 race for charities around the world.
Runners can still participate in the 2011 marathon though more than 90 affiliated non-profits. Go to chicagomarathon.com for charity program details.
