That's weird, she was in about 13th place at 14 miles, missed the 17 mile mat, then finished in 19th place. If she cut the course, she sure did it in a round about manner. They should talk to the six people who passed her. Guys tend to remember passing a woman at the front.
Not only that, but with a time of 1:37:38 at the 14 mile mark, she would have been the leading woman at that point... strange for someone to decide to cheat when they are already leading.
