But in the spring of 2021, after a workout on a rowing machine, Mr. Galloway was overcome with dizziness and fatigue. It was the onset of a heart attack, which progressed to heart failure. During another episode a week later, which occurred in a hospital, his heart stopped pumping altogether for four and a half minutes. It took two different defibrillators to bring him back to life.
Around this time, Amby Burfoot, a former editor of Runner’s World Magazine and another teammate of Mr. Galloway at Wesleyan, told him that he’d done some research and learned that Mr. Galloway had a chance of becoming the first person to complete a marathon in eight consecutive decades.
