Malone, who is running in the event for the first time, had a very scary moment after going into atrial fibrillation just a year ago.
I was just biking back from my friend's house to my apartment, which is something I do all the time," recalled Malone. "And my watch flagged that my resting heart rate was over 160. So I kind of was just like, that's so bizarre. I've never seen anything like that before. So I got about 20 blocks further and then it started like blaring, you've gone into AFib."
Malone had an extremely rare and extremely irregular heartbeat. Doctors gave her medication designed to stop her heart completely.
"I was headed towards either having a stroke or cardiac arrest," she added.
Doctors at Mount Sinai told Eyewitness News it wasn't the first time they've seen a situation like Malone.
"We've seen a remarkable number of patients come in after they made a self-diagnosis of atrial fibrillation," doctors said. "About one-third of patients with atrial fibrillation have no symptoms, at least in the onset. So therefore, these devices (Apple Watches) have brought them to medical attention much earlier."
The frightening ordeal led Malone to change her ways, which included a 100-pound weight loss, focus on sleep and nutrition and running.
"It was all just kind of adding up and snowballing into what happened," Malone said. "I will never be in this position again if, if I have anything to do with it. So I just made a complete life all over change."
The life change has led Malone to the marathon exactly a year after being discharged from the hospital.
Malone will be running with the American Heart Association, New York City team to raise money and advocate for heart health.
