Jeffing Walk-Run Trend Rising
"Jeffing"—the walk-run fitness trend—is gaining popularity as a sustainable way to build endurance, lose weight, and boost stamina, especially for beginners. The method is being praised by experts as an effective approach that reduces injury risk while still delivering cardiovascular benefits. The technique alternates between running and walking intervals throughout a workout.
The "Jeffing" method was developed by American Olympian Jeff Galloway in 1973. A member of the 1972 U.S. Olympic team in the 10,000 meters, Galloway created his signature "Run-Walk-Run" technique while training a group of beginners, all 22 of whom finished a 5K or 10K without injury after 10 weeks. Galloway, who passed away in February 2026 at the age of 80, used the method to remain a competitive runner and claimed to be injury-free himself since 1978. The core of the method involves strategic, planned walk breaks from the very start of a run. The specific ratio of running to walking is adaptable based on an individual's pace and goals. For instance, a runner with a 10-minute mile pace might use a ratio of 90 seconds of running followed by a 30-second walk, while someone with a 14-minute mile pace might alternate between 30 seconds of running and 30 seconds of walking. Proponents report that the technique helps manage fatigue, allowing runners to cover longer distances and recover more quickly. The walk breaks are intended to be short and strategic, not taken only when exhaustion sets in. This approach breaks the race or run into manageable segments, which can provide a significant mental boost. Multiple studies have suggested that the run-walk method can yield race results comparable to continuous running, but with less physical toll. A study in the *Journal of Science and Medicine in Sport* found that marathoners using a run-walk strategy had similar finish times to those who ran continuously, but they reported significantly less muscle pain and fatigue. Jeff Galloway's own data, collected from over 10,000 runners, indicated that his method can lead to faster times across various distances. His research suggests an average improvement of 7 minutes in a half marathon and over 13 minutes in a full marathon for runners who switch from continuous running to the Run-Walk-Run strategy.
