Dave McGillivray, the Boston Marathon Race Director, is celebrating the 40th anniversary of his run from Medford, Oregon to Medford, MA to benefit the Jimmy Fund. Today, he’ll mark the anniversary the same way he finished the original run.

Dave is leaving Medford City Hall at 10:30 and will run the seven miles to Fenway Park and do a lap inside the hallowed ballpark, before the Red Sox game against the Indians.
