More than Half of Somerville Residents in Marathon Without Finish Times

Of the 163 residents registered to run in the 2013 Boston Marathon, 77 had received finish times and 86 had not received finish times, according to the Boston Athletic Association's athlete tracker website.

These numbers were as of about 5:15 p.m. Monday.
