Jeff Galloway, the 1972 U.S. Olympic runner who revolutionized distance running with his run-walk-run method, died Wednesday at age 80 after suffering a hemorrhagic stroke in Pensacola, Florida. The former Olympian's innovative approach made running accessible to millions of everyday athletes, inspiring countless runners to complete marathons and half marathons they never thought possible.

Galloway's run-walk-run strategy emerged in 1974 when he taught a running class at Florida State University. He discovered that incorporating walking breaks reduced injury risk, conserved energy, and kept runners together regardless of experience level. His method proved so effective that he even walked through water stations during the 1980 Houston marathon, finishing in 2:16:35 - faster than his previous run-only attempts.

Throughout his career, Galloway authored numerous books, consulted for runDisney events, and hosted running retreats. His influence extended far beyond elite athletes, touching everyday runners like 70-year-old Karen Bock-Losee, who completed multiple half marathons after discovering his training philosophy. Fellow running coach Bobby McGee noted that Galloway's approach democratized the sport, making it accessible to people who previously thought running was beyond their capabilities. Galloway is survived by two sons and six grandchildren.
