April 15 is often a day of dread for many as income taxes can no longer be put off , yet there is an event that will draw at least half a million people that will be cheered by the events of the day, the annual Boston Marathon.

While you may not be able to get to Bean Town to watch the 117th running of the event there is now an app available from AT&T and the Boston Athletic Association that runs the event that will enable you to track the runners and their times during the race.

Marathon apps are nothing new; the New York Marathon has had one available for several years and there are any number of running apps that allow you to post your route and time in real time, but this is still a good way for those who are interested in tracking the times from the event.

However the app and other related programs from AT&T are part of a larger weekend event that the company is using to offer free service to runners, friends and family attending Marathon Weekend.

The marathon app enables users to select up to 10 runners that are participating in any of the races that day and it will provide updates from the 10K point, the halfway point of 13.1 miles at Wellesley Center, the 30K point and the finish line.

For the true athletes that are actually racing there is the Athlete Alert Program that permits runners to automatically update their progress along the course. Runners register prior to the race and as they pass specific points automatic messages are sent out to e-mail addresses, smartphones and other devices.

Other features from the weekend include free commemorative photos at the finish line for both runners and fans and the network will provide free calling centers for race finishers to contact friends via phone or text.
