Run Walk Pace Calculator

Updated 12 Nov 2026 · Source: NIST unit conversion factors ↗

Set how many minutes you run and walk in each cycle, your running pace and your walking pace, then pick a race. The calculator gives your real average pace and a finish time for the run-walk method.

Worked example

One cycle: 4.0 min running covers 0.381 mi; 1.0 min walking covers 0.059 mi.
5.0 min ÷ 0.440 mi = 11:22 per mile

Average pace for run and walk ratios (run 10:30, walk 17:00 per mile)

Run : walk (min)	Average pace	5K	Half
2 : 1	12:02	37:23	2:37:45
3 : 1	11:37	36:04	2:32:12
4 : 1	11:22	35:19	2:29:03
5 : 1	11:13	34:51	2:27:01
8 : 1	10:58	34:04	2:23:45
9 : 1	10:55	33:55	2:23:07
1 : 1	12:59	40:20	2:50:11

Why you can't just average the two paces

With the run-walk method you split time, not distance. In each cycle the running part covers more ground per minute than the walking part, so a simple average of the two paces is wrong.

The calculator finds how far each part of one cycle takes you, adds them up, and divides the cycle time by that distance. With the default 4 minutes of running at 10:30 per mile and 1 minute of walking at 17:00, one 5-minute cycle covers 0.440 miles. That is an average of 11:22 per mile, and a half marathon in about 2:29:03.

Walk breaks cost less than you might think

In the default setup you run 80% of the time, yet your average pace is only 52 seconds per mile slower than your running pace. Look at the table to see how other ratios compare at the same paces.

Going from 4:1 to 9:1 saves just 27 seconds per mile. Going the other way to 1:1 costs much more: the average drops to 12:59. Small changes in the walk share matter less than the speed you hold while running.

Your walking pace matters too

A slow stroll during the walk break drags the average down. A brisk walk keeps it close to your running pace. Try changing the walking pace from 17:00 to 15:00 in the tool and watch the finish time move.

If you are not sure of your walking pace, time yourself over a known distance or use the walking pace calculator.

Setting up intervals for a race

To see how your average pace compares with even pacing, enter the same goal on the half marathon pace chart.

Use a watch or phone timer that beeps at each switch, so you do not have to count.
Start your walk breaks from the first cycle, while you still feel fresh.
Keep the running part at an easy, steady pace instead of speeding up to make up time.
Walk to the side of the course and check behind you before slowing down.

Using run-walk while you build up

Short running segments with walk breaks are also how beginner 5K walk-run programs begin. If you are working toward running a whole 5K without stopping, our 5K training plan page has a simple run and walk progression.

Questions

Is the run-walk method slower than running the whole way?

At the same running pace, yes. The calculator shows the size of that gap, so you can decide whether the breaks are worth it for your race.

What ratio should I use?

There is no single right ratio. Pick one you can repeat for the whole distance at an easy effort, and test it on long training runs before race day.

Can I enter seconds instead of minutes?

Yes. Use decimals: 30 seconds is 0.5 minutes, so a 30 second walk break is 0.5.
