The man was reportedly running with his daughter.
At the time of the collapse, it was 81 degrees at the airport, and the humidity was around 71 percent.
Officials had set the race day alert condition to red due to the expected high heat and humidity. Runners were encouraged to begin hydrating early to prepare their bodies for the race.
