Jeff Galloway dies at 80: cause of death of the Olympic athlete who transformed the way millions of runners train

For decades, runners who once believed marathons were out of reach found themselves crossing finish lines because of Jeff Galloway.

The 1972 U.S. Olympian did more than compete at the highest level of his sport. He changed how everyday people thought about running.

Galloway, who died Wednesday at age 80 after suffering a hemorrhagic stroke, built a philosophy around the idea that endurance did not require constant suffering.

His daughter-in-law, Carissa Galloway, said he died at a hospital in Pensacola, Florida. In the days leading up to his passing, supporters flooded social media with messages of encouragement after his family announced he had undergone emergency neurosurgery on Feb. 20 and invited the public to share their support.

The outpouring reflected the reach of a man whose impact stretched far beyond elite competition. Jim Vance, an endurance sports consultant in San Diego, described Galloway as transformative.

"He removed the barrier to entry, which was mostly mental," Vance told The Associated Press. "Running isn't supposed to be a suffer-fest. It should be something peaceful, something enjoyable, so people can enjoy running and not dread it."

Galloway's legacy traces back to both Olympic achievement and entrepreneurial instinct. Two years after competing in the 10,000 meters at the 1972 Games, he agreed in 1974 to teach a running class through Florida State University.

At the time, he had recently opened Phidippides, a store catering to runners, and saw the class as a way to introduce more people to the sport.

"None had done any running for at least five years. So we started walking with a few one-minute jogs," Galloway said on his website.

The structure was simple but revolutionary: alternate periods of running and walking to manage fatigue and confidence.

"I spent some time with each group, during the runs, to adjust the frequency of walk breaks so that no one was huffing and puffing -- even at the end," he noted. "Walk breaks kept the groups together. Everyone passed the final exam: finishing either a 5K or a 10K with smiles on their faces."

A philosophy built on sustainability, not suffering

The method evolved into what became known worldwide as run-walk-run. Galloway believed that strategic walk breaks reduced injury risk, preserved energy and helped runners maintain belief in themselves.

"I've been using them ever since," he said, "continuing to fine-tune the ratios of running to walking based upon pace per mile and individual needs."

He practiced what he preached. During the 1980 Houston marathon, Galloway walked through every water station and still posted a faster finish, 2:16:35, than he had in previous run-only 26.2-mile races, according to The New York Times.
