I Tried a 14:1 Run-Walk Ratio on My Long Run. Here’s What Happened

Last week, I made a decision after my half marathon long run, I decided I was officially committing to the run-walk method for this marathon training cycle.

If you missed that story, here’s the short version.

I had planned to run 21.1 km continuously for as long as I could during my training run. I made it to about 16.5 kilometres before everything started to unravel. My legs were tired, my mind was tired, and even though I tried introducing walk breaks at that point, it almost felt too late.

Those walk intervals weren’t helping me stay strong. It was just so incredibly hard to finish those last 3-4km.

After completing the run I had learnt my lesson: by waiting until I was already exhausted to take a walk break, I wasn’t preventing fatigue...I was simply delaying it until it became overwhelming.

So this week’s 23-kilometre long run became my first real test of the run-walk method.

Choosing the right run-walk ratio

One thing I didn’t expect was how much time I would spend thinking about the actual interval ratio.

For my previous two marathons, I used a 9-minute run, 1-minute walk strategy. It worked. It got me across two marathon finish lines.

But this year, I have a different goal. I don’t just want to finish. I’d like to improve on both of my previous marathon times AND do so with a smiling across the finish line.

That meant I started wondering if slightly longer running intervals would reduce the total number of walk breaks while still keeping fatigue under control.

My coach and I went back and forth between a few different options:

• 9 minutes running / 1 minute walking
• 14 minutes running / 1 minute walking
• 19 minutes running / 1 minute walking

Eventually, we settled on the middle option. Fourteen minutes running. One minute walking. 

How things can change from one week to the next

On this week's run as I approached 16.5 kilometers I recognized the exact spot where last week’s run had completely fallen apart. Something was definitely different this week.

Instead of negotiating and willing myself to just keep running…I felt strong. The pace was comfortable and in control.

Instead of wondering how much longer I could keep going, I realized I still had plenty left. And I was actually quicker than the previous week's continuous run.

The numbers surprised me

Sometimes we assume stopping to walk must make us slower.

This run proved the opposite.

Last week’s long run:

• 21.1 km
• Average pace around 7:05/km
• Started struggling after 16.5 km

This week’s long run:

• 23 km
• Finished in about 2 hours 37 minutes
• Average pace of approximately 6:50/km

Not only did I run farther, but I also averaged a faster pace.

In fact, I reached the half marathon mark several minutes faster than I did the previous week.

That’s the beauty of strategic walk breaks.

You give away one minute at a time, but you avoid giving away huge chunks of time later when fatigue forces you to slow down dramatically.

An unexpected bonus: fueling became easier

One thing I hadn’t considered before this run was how much simpler my nutrition strategy would become.

During every second walk interval, I ate either an energy gel or an XACT Energy Fruit Bar.

Between those fueling breaks, I focused on my hydration.

Because the intervals happened at predictable times, everything became incredibly easy to remember.

Around the 30-minute mark? Fuel.

Around the hour? Fuel again.

No mental math.

No wondering when I last ate. No forgetting because I was too focused on running. As the kilometres add up, our brains get tired too. Having a simple routine removes one more decision from an already demanding run.

Was it perfect?

Not quite. The final kilometre definitely felt harder. But honestly…Every long run eventually reaches the point where your brain starts negotiating.

“We’re basically done.”

“Surely we can stop now.”

“Twenty-three kilometres is close enough…”

I don’t think that feeling disappears. I think it’s simply part of endurance training. The difference this week was that I reached that point much later than I did last week.

What I’ll be doing next

One successful run doesn’t automatically prove I’ve found my perfect marathon strategy. I still have several long runs before race day.

There will be hot days. Bad days. Days where nothing feels easy. But this run gave me confidence that starting my walk intervals early isn’t a sign of weakness.

It’s a strategy.

One that helped me run farther, faster, and feel stronger at the exact point where I struggled only a week earlier.

And that’s a pretty convincing reason to keep testing it.

If you’ve been resisting the run-walk method because you’re worried it’ll slow you down, maybe it’s worth asking a different question.

What if those one-minute walk breaks aren’t holding you back?

What if they’re the very thing that helps you finish stronger?
