1968 Boston Marathon champion Amby Burfoot holds up a singlet during a news conference in Boston, Thursday, April 17, 2014. Burfoot will wear it when he runs next week's Boston Marathon for the Martin Richard foundation MR8. Martin Richard was one of the three victims killed in the 2013 Boston Marathon bombings. Burfoot has run the Boston Marathon every 5 years since his 1968 victory, but was stopped from completing the race in 2013 because of the bombings. (AP Photo/Elise Amendola) less
