RACE DAY ATHLETE TRACKING ON B.A.A. WEBSITE

Visitors to www.baa.org on April 21 will be able to track official runners in the Boston Marathon as they pass eleven checkpoints along the race course. Checkpoint data will be transmitted via the ChampionChip timing and scoring device, worn on the runners' shoelace, and made available to the public on the B.A.A.'s website.

By entering in an athlete's bib number or first and last name on the B.A.A.'s Athlete Tracking website, users of the feature can follow a runner's progress as they cross the start, 5K, 10K, 15K, 20K, half marathon mark, 25K, 30K, 35K, 40K and finish line.

Look for the Athlete Tracking feature on the B.A.A.'s website on April 21.
