Is run-walk a good way to run a marathon?
Yes, it is a credible option, especially for first-timers. In the one randomized trial, run-walkers finished in similar times to continuous runners and reported much less exhaustion and muscle pain. The trade-off is about 6% more energy per kilometre, and the popular run-walk ratios are convention rather than tested.
What to do
- If you want to try run-walk, start at around 3 minutes running to 1 minute walking and lengthen the running segments over time, up to about 10:1. These ratios are convention.
- An alternative is a 1-minute walk about every 2.5 km. This is also convention.
- Practise your exact run-walk pattern in long runs before race day.
- Before starting a marathon block, make sure you have finished a half marathon or can run for 90 minutes without stopping. If not, build a base first.
- As a first-timer, a peak of about 4 runs and 45–55 km a week is a common target. A 3-run week is a reasonable variant.
The trial
Only one randomized trial has tested run-walk in a full marathon (Hottenrott and colleagues, 2016). It included 42 runners, split into a run-walk group and a group that ran continuously.
- Finish times were similar: 4:14 and 4:08. The difference was not statistically significant.
- Run-walkers reported markedly less exhaustion and muscle pain after the race.
So for this group of runners, walk breaks did not cost a meaningful amount of time, and they made the race feel easier on the body. It is one trial with 42 people, which is why the grade is B and not higher.
The cost: about 6% more energy
Walk breaks are not free. Frequent walk breaks cost about 6% more energy per kilometre than continuous running (run-walk energy cost study, 2021).
That matters for fuelling. If your marathon takes more than four hours, you still need regular carbohydrate. See how many carbs per hour. Finishers slower than four hours also face a higher risk of drinking too much (Almond and colleagues, 2005), so drink to thirst rather than at every station; see how much to drink.
Run-walk ratios
The best-known approach comes from Jeff Galloway’s run-walk method. The defaults in our source report’s rule set (SP-9) are:
- Start at 3:1, meaning 3 minutes running and 1 minute walking.
- Progress towards about 10:1 as fitness improves.
- Or use a 1-minute walk every 2.5 km or so.
These ratios are coaching convention. The trial supports run-walk as a strategy, not any particular ratio.
As an example of the distance-based option: a marathon is 42.2 km, so a walk every 2.5 km gives about 16 walk breaks.
How to choose, as our suggestion rather than a tested method: try your planned ratio in two or three long runs at goal effort. If the walk breaks leave you feeling fresher late in the run without slowing you much, keep them. If they break your rhythm, lengthen the running segments. Decide well before race day, and don’t switch strategy on the start line.
Galloway’s marketing claims a success rate above 99% for his method. That figure is marketing copy, not a research finding.
Why this matters for first-timers
First marathons carry real risk of injury and of giving up.
- Among 720 first-time New York marathoners, about half reported a minor injury, and roughly 7–10% had an injury that stopped them racing. Having completed a half marathon before, and having done a longer longest run, were both protective (Toresdahl and colleagues, 2020).
- Among novice runners, 29.5% quit within 26 weeks, and 48% of those who quit gave injury as the reason (Fokkema).
That makes anything that keeps new runners healthy and enjoying it worth taking seriously. Run-walk is one such tool. The training itself can be good for you too: six months of novice marathon training reduced artery stiffness by the equivalent of about four years of vascular age (Bhuva and colleagues, 2020).
Two related defaults from the rule set, both graded C:
- Readiness (SP-7): finish a half marathon or a continuous 90-minute run before starting a marathon block. If you can’t yet, add a base-building phase first.
- Volume (SP-8): about 4 runs a week and a peak of about 45–55 km a week, with a 3-run option. The data on how often first-timers should run conflict.
Whatever you do, keep each run within 10% of your longest run of the past 30 days; see the long-run injury rule. For long-run length in general, see how long your long runs should be.
What we don’t know
- The evidence is a single trial of 42 runners. It needs repeating, ideally in larger and more varied groups.
- No ratio has been tested against another. The 3:1 and 10:1 figures are convention.
- Whether run-walk lowers injury risk in training is not shown by the evidence we rely on.
- The 6% energy cost comes from one study.
