Run Walk Calculator

The run-walk calculator projects your finish time when you use the Jeff Galloway run-walk-run method — alternating short bursts of running with planned walk breaks. Enter your run interval, walk interval, target distance, and the paces you hold for each, and it returns your projected finish time, average pace, and the number of cycles you'll complete.

The Run-Walk-Run Method

Popularised by Olympian Jeff Galloway, the method inserts walk breaks before you fatigue, not after. By resting the running muscles at regular intervals, many runners cover the same distance feeling fresher — and sometimes faster — than running continuously. It is especially popular for marathons, injury comebacks, and beginners.

How the Projection Is Calculated

Each cycle covers a fixed distance and takes a fixed time. The calculator works out distance per cycle, then how many cycles fit the target distance:

Average Pace by Run:Walk Ratio

Assuming a 6:00 min/km run pace and a 9:00 min/km walk pace, the blended average pace depends on the ratio:

Choosing Your Intervals

• Faster runners: longer run segments and short 20–30 second walks preserve momentum.
• Beginners / long races: shorter run segments (1–2 minutes) make the distance feel manageable.
• Consistency matters: take the walk break on schedule from the start, not only when you tire.

A Note on Walk-Break Efficiency

The walk break costs less time than runners fear because it prevents the dramatic slowdown that hits continuous runners late in long races. Many run-walkers post faster overall times than they would running straight through, simply by avoiding the final-kilometres collapse.

Note: This is a projection assuming you hold your stated paces evenly across every interval. Real results vary with fatigue, terrain, and conditions. Informational only and not a substitute for coaching or medical advice.
