CONEY ISLAND, Brooklyn (PIX11) — A man who participated in the Brooklyn Half Marathon on Saturday died, officials said.

The runner was 32-year-old Brooklyn resident David Reichman, according to the NYPD. Reichman collapsed after finishing the race, a spokesperson from the New York Road Runners said. He was taken by on-site medical staff to a hospital where he was pronounced dead.

Reichman possibly suffered a cardiac failure, police said. A medical examiner will determine his exact cause of death.

Sixteen people who participated in the race were taken to a hospital, according to the FDNY. Five suffered serious injuries, eight people had non-life-threatening injuries and four people sustained minor injuries.

New York Road Runners said they had medical staff on standby from start to finish throughout the racecourse. They also said they closely monitored weather conditions leading up to and during the race, with temperatures ranging from the low 60s to high 70s.

A heat advisory cautioning that hot temperatures and high humidity could spark heat illnesses was in effect throughout New York City until 8 p.m. Saturday. Temperatures exceeded 80 degrees Fahrenheit as of midday in Brooklyn.

“We are deeply saddened by the passing of a participant following the 2022 RBC Brooklyn Half. Our thoughts and sympathies are with the runner’s family and those close to them,” New York Road Runners said in a statement. “The health and safety of our runners, volunteers, partners, and staff remain the top priority for NYRR.”
