BOSTON — Tucsonan Shirley Reilly edged Japan's Wakako Tsuchida during a sprint to the finish line to win the women's wheelchair division of today's Boston Marathon.
Reilly finished in 1 hour 37 minutes and 36 seconds, one second ahead of defending champion Tsuchida.
Last year, Tsuchida beat Reilly by nearly seven minutes.
Reilly and Tsuchida battled throughout, with Tsuchida briefly breaking away around the 18-mile mark before Reilly closed the gap.
Diane Roy of Canada finished third, five minutes behind Tsuchida.
Reilly, a long-time member of the University of Arizona wheelchair racing team, also won the Los Angeles Marathon last month.
A native of Alaska, Reilly was a member of the 2004 and 2008 U.S. Paralympic team. She will also represent the U.S. in the 2012 games in London this summer.
