Bobbi Gibb, she had run Boston in 1966 as well, but on both occasions she hadn't entered and had waited in nearby bushes for the race to start and joined the crowd.

Whilst Switzer's time at Boston in 1967 was fairly unremarkable, she went on to become a very good marathoner, winning the New York Marathon and setting a PB of 2:51 at Boston, she also did huge amounts to promote women's distance running around the world and was instrumental in the Marathon becoming an Olympic event for women in 1984.
