There were two easy predictions for the women’s 2-mile race at the New Balance Indoor Grand Prix on Saturday: Three-time Olympic gold medalist Tirunesh Dibaba would blow away the field at the Reggie Lewis Track and Athletic Center, while high school phenom Mary Cain would set the national high school record.

Both Dibaba and Cain raced with a competitiveness and a confidence that turned those predictions into certainties well before they crossed the line.
