A 30-year-old man died near the finish line of the RBC Brooklyn Half Marathon on Saturday as New Yorkers headed to Coney Island Beach on the hottest May day ever recorded in the Northeast region.

The runner, who has yet to be identified, collapsed shortly before 9 a.m. close to the finish line in Coney Island as temperatures soared from below 60F at dawn to nearly 80 degrees by morning, with New York City expected to see a high of 93F on Saturday, the New York Times reported.

He and five other runners participating in the 13.1 mile race were hospitalized and taken to Coney Island Hospital, where he was pronounced dead.

Three of the other runners were listed in serious condition, while the remaining two were reported with minor injuries, the New York Fire Department said.

While race organizers warned participants of the heat advisory in place for New York, the first one in 16 years, it is not yet clear if the heat led to the death and injuries, officials said.

The death at today’s Brooklyn Half Marathon was the first time since 2014 where a participant in a half-marathon died in the city.

New York City Mayor Eric Adams had also issued a warning about Saturday’s heat, saying beaches are still closed and asking residents to check up on neighbors.
