A Long Island doctor died after he got poor medical care during a midnight run, his family claims.

Anesthesiologist Martin Gottlieb was racing in the New York Road Runners New Year’s Eve run in Central Park two years ago when he had a heart attack, according to a lawsuit.

But the medical staff provided by the Road Runners, sponsor Emerald Nuts, Seniorcare Emergency Medical Services, and those Gottlieb later encountered at St. Luke’s Hospital, provided substandard care, the family charges.

Race organizers hired staff who were “careless, unskillful, negligent and who did not possess the requisite knowledge and skill of medical, emergency medical, nursing, paramedic, life support and health-care professionals,” according to the Manhattan Supreme Court lawsuit.

The family is seeking ­unspecified damages.
