Well, the reason for Rosie’s freshness, it later transpired, was that she had entered the race twenty minutes from the finish, having used regular transport to get there from the start. She had missed all the checkpoints, but in view of the fact that she was a Cuban-American and a woman to boot, the race marshals blamed themselves for missing her. For some strange reason we have never heard of Rosie since then, but now, age 66, I hear she’s doing fine.
Might this have goaded her into action?
