Run/Walk Interval Calculator
Enter a total duration and your run:walk ratio to see how many intervals you’ll do and how the time splits between running and walking.
Your run/walk breakdown
Each cycle runs first, then walks; a final partial cycle counts as one more interval. The Galloway run/walk/run method uses planned walk breaks from the very start of a run to manage fatigue — the ratio is yours to set.
Structure makes the session easier
Planned walk breaks turn a daunting continuous run into a series of short, repeatable efforts. Knowing in advance that you’ll do, say, six run/walk cycles makes a 30-minute session feel achievable, and the breakdown lets you set your watch or app before you head out.
It also suits the reality of running with young kids: the walk segments are natural moments to check on a passenger, adjust a stroller, or simply catch your breath.
Frequently Asked Questions
What is the Galloway run/walk method?
Devised by Olympian Jeff Galloway, it inserts planned walk breaks into a run from the very beginning — for example run four minutes, walk one minute, repeat. Taking the breaks before fatigue sets in helps many runners cover more distance with less strain and quicker recovery.
How does this calculator work?
You enter your total workout length and your run:walk ratio. It lays that ratio across the session, running first then walking each cycle, and reports the number of intervals plus your total time spent running and walking. A final partial cycle counts as one more interval.
What run:walk ratio should I use?
It depends on your fitness and goal. Newer runners often start around run 1:walk 1 or run 2:walk 1 (minutes), while more experienced runners might use run 4:walk 1 or longer. There is no single correct ratio — pick one you can sustain and adjust from there.
Is run/walk only for beginners?
No. Plenty of experienced runners use run/walk for long runs and even races to control effort and reduce fatigue. It is also a practical way to return to running gently, and to fit a session around a nap or a stroller loop.
Do the walk breaks make me slower overall?
Not always. Because the walk breaks keep fatigue in check, many runners hold a stronger running pace through the session and finish with a similar or better overall time than running straight through — especially over longer distances.
