“Saúde perfeita, físico perfeito, 24 anos de idade,” her father, Steve Apa, told The New York Times regarding his daughter, Rachel Apa, who tragically died hours after collapsing during the New York City Marathon.
Rachel Apa, a 24-year-old first-time marathon runner from Lewisberry, Pennsylvania, collapsed in Central Park approximately 3.2 kilometers short of the finish line during the race. She was rushed to Mount Sinai Medical Center, where medical staff attempted to revive her for over six hours before she was pronounced dead at approximately 9:40 p.m. Hospital physicians determined the cause of death to be rhabdomyolysis, a severe medical condition where damaged muscle tissue releases proteins and electrolytes into the bloodstream, which can compromise vital organs, including the kidneys and heart, and potentially cause fatal arrhythmias or cardiac arrest.
The Fatal Collapse in Central Park
The tragedy unfolded on Sunday as Rachel joined more than 61,000 registered participants in the New York City Marathon, running the course that threads through all five of the city's boroughs. Having played field hockey at the NCAA Division I level for Bucknell University, she had trained for months for the event and was also running to raise funds for Parkinson’s disease research in memory of her grandfather. While her father tracked her progress from Pennsylvania using a race monitoring application, her mother, Michelle Apa, waited near the 40-kilometer mark.
Rachel collapsed shortly before reaching the 39-kilometer marker, at approximately 1:33 p.m. Spectator Micaela Nicholas rushed to her side and checked her pulse, finding no signs of life. Three bystanders administered basic life support before marathon medical personnel arrived with a defibrillator. An ambulance subsequently transported her to the Mount Sinai medical center.
Medical Context of Exertional Rhabdomyolysis
Rhabdomyolysis occurs when skeletal muscle cells break down rapidly, releasing substances such as proteins and potassium into the bloodstream. These substances can compromise vital organs, including the kidneys and heart; excess potassium disrupts cardiac electrical activity, triggering potentially fatal arrhythmias.

Exertional rhabdomyolysis typically links to high-intensity physical activity for which an individual’s body is insufficiently prepared, though it also appears among endurance athletes, CrossFit practitioners, and participants in group exercise settings. A 2021 study highlighted instances among young, healthy women driven by group pacing pressures to exceed individual capacities.
New York Road Runners Expresses Grief over Tragic Death
New York Road Runners released a statement expressing profound grief over the tragedy. “We are deeply saddened by the death of one of our runners after yesterday’s race. Our thoughts and sincere condolences are with the family, friends, and the entire running community,” the organization stated. The group noted that the previous fatality during the event occurred in 2024.
