FILE - In this Aug. 29, 1978, file photo, David McGillivray reaches out to fans at Fenway Park in Boston as he completes a 3,400-mile, 80-day cross country run to raise funds for a children's cancer research charity sponsored by the Boston Red Sox. McGillivray, who later became race director of the Boston Marathon, has quietly stolen away after the race is over and workers are sweeping up the confetti, to run the entire Boston Marathon course in the dark. On Monday, April 17, 2017, he will run it for the 30th consecutive time at night. (AP Photo/Chip Maury, File)
