Official runners of the Boston Marathon can register to send friends and family automatic updates on their progress along the course using the AT&T Athlete Alert Program.  Messages will be automatically delivered to any device capable of receiving short messages, such as a digital cellular phone, pager, hand-held device, or e-mail address.  Alerts will be broadcast from the 10-kilometer, half-marathon, and 30-kilometer marks, as well as the finish, when the runner passes those locations.
