   Marathon, to be held on October 7th, will be the first marathon with the
   capability to deliver automated updates on runners? times and breaking
   news by phone, e-mail, pager, or wireless device.

   "We are very proud to be the first marathon to offer this unique,
   multi-channel technology," said Carey Pinkowski, executive race director
   of the LaSalle Bank Chicago Marathon. "We have always made a commitment
   to enhance the race experience and create a world-class event. Friends
   and family ? as well as marathon fans everywhere ? will now be able to
   follow the progress of their favorite runners as they complete the
   26.2-mile challenge."

   The LaSalle Bank Chicago Marathon has a long-standing tradition of
   utilizing technology to enhance the race experience for runners and
   fans. In 1998, the ChampionChip timing and scoring system made its
   debut. By 2000, individual splits were posted to the Internet every
   seven minutes, which enabled friends and family to follow their favorite
   runners directly from their personal computers. This tracking capability
   is now being expanded to mobile communications devices.

   The LaSalle Bank Chicago Marathon is one of the premier races in the
   world. From 1996 to 2000, the number of registered runners grew
   three-fold from 10,925 to 33,171. In addition to the amazing growth of
   the field, The LaSalle Bank Chicago Marathon is now one of Chicago?s
   favorite annual traditions with more than 900,000 spectators lining the
   race course in 2000.
