BOSTON (AP) – Three-time Boston Marathon winner Uta Pippig will be become a U.S. citizen on Saturday – and will run her first race as an American on Sunday.

Pippig will be sworn in at a ceremony at the Hatch Shell before a rehearsal for the Boston Pops Fourth of July concert. The next morning, she’s entered in the Minuteman Classic, a five-mile road race in Concord.

Born in East Germany, Pippig is the only woman to have won three consecutive Boston Marathons since the women’s division was created in 1972. She won the first in 1994, setting what was then a course record of two hours, 21 minutes and 45 seconds. But she’s best known for her grueling come-from-behind win in 1996.

She last ran in the Boston Marathon in 1997, finishing fourth.
