Registration is moving at a rapid pace toward the race field capacity of 12,500 runners for the Sept. 9 Banco Popular Chicago Half Marathon, prompting event organizers to expect a second consecutive sellout. The 2006 event sold out well in advance of race day.

Touted by Runner's World magazine as one of the Top 10 Half Marathons in the United States for two straight years, registrations for the 2007 event are more than 100 percent ahead of last year. The record registration numbers are evidence of the exploding popularity of the 13.1 mile half marathon distance. The Banco Popular Chicago Half Marathon has steadily grown since its inception in 1996, and the event has become one of the most anticipated long distance races in the Midwest.

The event's official training program, Chicago Roadrunners, begins on June 16. The 13-week training program is designed to help to help both experienced and novice runners, joggers and those interested in becoming more fit reach their goal in a fun and educational setting. Saturday morning training runs start on June 16.

With record crowds expected for this year's event, participants are strongly encouraged to take advantage of the race day roundtrip Shuttle Service, provided by the Chicago Sport and Social Club. Roundtrip shuttles will once again pick up and drop off from four locations: Kincade's Bar and Grill in Lincoln Park (950 W. Armitage); New Balance Chicago (2369 N. Clark, at Fullerton); the Addison Red Line 'L Stop in Wrigleyville (at Sheffield); and The Holiday Inn Chicago Mart Plaza (350 N. Orleans St.).

Also returning for the second year is the Banco Popular Chicago Half Marathon's partnership with Special Olympics Chicago. In 2006, the generosity of race participants helped to raise more than $30,000 for the Chicago-based charitable organization.
