RUN/WALK CALCULATOR · ANY DISTANCE
Run/walk calculator
Your average run/walk pace is the time of one run-and-walk cycle divided by the distance it covers. Running for 4 minutes at 6:00 per km and walking for 1 minute at 12:00 per km covers 0.75 km per 5-minute cycle. That works out to 6:40 per km and a marathon finish of 4:41:10. Enter your own intervals and paces below, or start from a goal time to get the full schedule.
Whole run minutes from 1 to 60 and whole walk seconds from 1 to 3600. The cycle repeats from the start, and the last cycle stops at the finish.
Each cycle of 4:00 running and 1:00 walking covers 0.750 km at your paces. This finish time is worked out from those paces over the full marathon (42.195 km); it is not a prediction. Open this plan with checkpoints and a pace band.

The schedule runs from the start gun to the finish time calculated from your paces.

|---|---|---|---|
| 1 | 0:00:00 | 0:04:00 | 0:05:00 |
| 2 | 0:05:00 | 0:09:00 | 0:10:00 |

| 57 (last, partial) | 4:40:00 | no walk | 4:41:10 |
The finish time does not divide evenly by the cycle, so the last cycle stops at 4:41:10. The finish comes 1:10 into its run, so it has no walk.
Every cycle, the last partial one and your walk total
We checked the top 5 US and UK results for “run walk calculator” on 24 September 2026. Most return a finish time, a blended pace or a required run pace. Only one lists each cycle with run and walk totals, and its plan does not add up: for a 5:00:00 marathon at 4:1 it ends at 43.008 km and 5:05:00. In this calculator, a 4:00:00 marathon with a 4-minute run and 1-minute walk is exactly 48 cycles: 3:12:00 running and 0:48:00 walking. Another calculator in the top 5 gets the required running pace wrong: for a 12:00 per mile average with 4:00 running and 1:00 walking at 16:00 per mile, it gives 11:00 per mile. The correct answer is 11:17.6.
How the calculation works
- Distance per cycle = run seconds ÷ run pace + walk seconds ÷ walk pace (240 ÷ 360 + 60 ÷ 720 = 0.75 km in the example).
- Full cycles = race distance ÷ distance per cycle, rounded down (42.195 ÷ 0.75 = 56 full cycles, 42 km in 4:40:00).
- The last 0.195 km falls inside a run interval, so it takes 0.195 × 360 = 70.2 s. Finish: 4:41:10.
- Average pace = finish time ÷ distance. The finish can land in a run or a walk; the calculator handles both.
In goal-time mode the tool works the other way: it schedules your intervals from the start gun to your goal time. In the final cycle the run comes first, and the walk gets whatever time is left before the finish. The checkpoint splits and the pace band include the walk breaks.
Limits
The calculator works only from the paces you enter. It does not know your fitness, the course or the weather, and it does not model walking through aid stations. Jeff Galloway has taught planned walk breaks since 1974 as his Run Walk Run method. This tool is independent and does not recommend a ratio.
