Longtime Marathon director faces security, health tests

Dave McGillivray has five kids of his own, ranging in age from 23-year-old Ryan to 4-year-old Chloe, enough to keep any father busy. But each spring, as longtime director of the Boston Marathon, McGillivray finds that his horde grows to thousands.

He feels an almost paternal responsibility for each of his runners, never so much as this year’s field of 36,000 men and women, ranging in age from 18 to 83. All the runners matter to him, from the first one to fly over the finish line to the last one to straggle in.
