It was a race to save his life.

A marathon trainee dodged death on the running course over the weekend, thanks to a pair of fast-acting NYPD police officers who were hailed as heroes on Wednesday.

The 44-year-old man, who didn’t want to be identified, was nearing the end of an 18-mile loop in Central Park on Sunday when he suddenly collapsed in cardiac arrest near West 74th Street and West Drive.
