SAN JOSE, Calif., Oct. 16 /PRNewswire/ -- The Metro Silicon Valley Marathon® announced today that the second annual Comerica Corporate Challenge will take place on Sunday, Oct. 29 as part of the 2006 event.

Twenty companies are expected to field teams of runners at several distances, including the half-marathon, the distance at which the winner of The Comerica Cup, which goes to the "Fastest Company in Silicon Valley," will be determined.

Genentech will be defending its 2005 "Fastest Company in Silicon Valley" title, when its best three half-marathoners finished the San Jose-to-Los Gatos course in a cumulative time of 4:16:37. Team Yahoo! won the prize for the biggest team of runners in 2005, with 29 participants in the marathon, half-marathon and 5K race, and Team Apple walked away with the "Spirit" title. In 2005, 150 runners from 15 companies, including Cisco, Hewlett-Packard, IBM, Intel, Lockheed-Martin, Oracle, and Sun Microsystems, participated in the inaugural Comerica Corporate Challenge.

In addition to the trophies and bragging rights, the 2006 Comerica Corporate Challenge will feature a donation of $2,250, courtesy of Comerica Bank, to The Health Trust's Wellness, Education & Prevention Fund in honor of the winning teams. This money will directly fund programs that advance wellness in the Santa Clara County community, including The Health Trust's Children's Dental Services, Healthy Silicon Valley, Aids Services and The Women's Health Fund; as well as to other select community non-profits.

"The friendly competition displayed by last year's teams was indicative of the spirit that makes Silicon Valley such a vibrant community," said Mike Fulton, president and CEO of Comerica Bank's Western Market. "It's great that even more companies are joining this year's competition for The Comerica Cup."

Metro Silicon Valley Marathon Race Director Doug Epstein said, "The Comerica Corporate Challenge adds a distinct Silicon Valley flavor to this prominent race. We are excited to see if Genentech, Yahoo! and Apple have what it takes to defend their crowns."
