BOSTON -- Joshua Cassidy of Canada won the men's wheelchair race at the Boston Marathon, comfortably beating the field in world-record time.
Cassidy, of Toronto, finished Monday in 1 hour, 18 minutes and 25 seconds, which beats the world record by two seconds.
Ernst Van Dyk of South Africa set the previous record in Boston in 2004.
The 27-year-old Cassidy led from the third mile and finished well ahead of last year's runner-up Kurt Fearnley of Australia. Fearnley finished second in 1 hour, 21 minutes and 39 seconds.
Cassidy said once he hit the top of the course's Heartbreak Hill, he switched the timer on his chair from distance to time and went for the record.
The race was far different from last year's tight finish, when the top three racers finished within a second of each other.
In the women's wheelchair division, American Shirley Reilly edged Japan's Wakako Tsuchida during a sprint to the finish line.
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.
