The runner who died during the Brooklyn Marathon was David Reichmann

The Brooklyn half marathoner who died on Saturday while finishing the race amid the heat has been identified as Flatbush resident David Reichman.

Reichman, 32, collapsed on the Ocean Parkway promenade on Brighton Beach Avenue near the finish line after suffering a possible cardiac arrest, according to the New York Road Runners club and the NYPD.

Reichman was rushed to Coney Island Hospital, where he was pronounced dead, according to New York police. The medical examiner will determine the cause of death.

The race with 22,000 runners – from the Brooklyn Museum through Prospect Park to Coney Island’s promenade – took place on an unexpectedly hot and humid day. The temperature at 9 am on Coney Island was already 70 degrees with 83% humidity, according to Fox Weather.

The event was held in person for the first time since the beginning of the pandemic. Saturday’s death was the first death in the race since 2014, when a 31-year-old runner fell to the ground after crossing the finish line.

The FDNY said 16 contestants were taken to hospital after the race, including the dead man and four others who were seriously injured.

A police officer told The Post on Saturday that four other people had fallen at the end of the race.

“Maybe an organizer or a health officer should have called because of the conditions,” the cop said.

In a statement issued Saturday, New York Road Runners said it had “medical staff deployed from start to finish during the race who are ready to respond immediately to the medical needs of all runners, spectators, volunteers and staff.”

“The health and safety of our runners, volunteers, partners and staff remains a top priority for the NYRR,” the group said. “In coordination and consultation with partners of city agencies and meteorological experts, the NYRR closely monitored the meteorological conditions that led to and during the competition.
