The day before the Boston Marathon, two marathon giants met off Boylston Street.

Joan Benoit Samuelson, a two-time winner of the Boston Marathon and the first Olympic women’s marathon champion, introduced herself to Mariko Yugeta, the first woman older than 60 to run a marathon in under three hours.

"I’m super nervous about meeting her; I’ve been thinking a lot about the questions I want to ask her,” Yugeta, 63, said before the meeting Sunday. "She’s run at a high level for a long time. What kind of things does she do to keep running now?”
