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.

Dibaba ran most of the race alone and nearly lapped the field, finishing three seconds shy of the meet record in 9 minutes 13.17 seconds. Cain, a 16-year-old junior from Bronxville, N.Y., took third overall, finishing in 9:38.68, topping the mark by more than 17 seconds.

She didn’t just break the scholastic mark, set by Melody Fairchild in 1991, she obliterated it with an impressive kick that is becoming a trademark.
