STRENGTH TRAINING & DISTANCE RUNNING: IS IT WORTH MY TIME?

You only have limited time. Is strength training a better investment than another easy run?

If you’re a distance runner, chances are you’ve asked yourself some version of this:

“If I only have limited time, shouldn’t I just run more?”

It sounds logical. After all, if your goal is to get better at running, the obvious answer is to… run.

But in reality, that’s where a lot of runners get stuck.

Because while running volume matters, strength training is one of the most underutilised tools in distance running — not just for injury prevention, but for actually helping you run faster, more efficiently, and more consistently.

And if you’re short on time, the truth is this:

Replacing one low-value run with one well-designed strength session is often a better trade than simply adding more kilometres.

Not always. But very often.

Why more running isn’t always the answer

A lot of recreational runners sit in a frustrating middle ground.

They run often enough to be tired…

but not strategically enough to keep improving.

They’re doing:

• a few steady runs

• maybe one hard session

• maybe a long run

• and then repeating the same pattern every week

And yet their pace stagnates, little niggles keep appearing, they feel weak on hills, they lose form late in races and they never quite feel “athletic”

That’s because running fitness isn’t just about your lungs and heart.

It’s also about how well your body can produce force, absorb force, stabilise under fatigue and repeatedly apply power into the ground efficiently

That’s where strength training comes in.

What strength training actually does for runners

Good strength training doesn’t turn you into Arnold Schwarzenegger.

It builds the physical qualities that make running easier, more durable, and more economical.

1. It improves running economy

Running economy is basically how much energy it costs you to run at a given pace. If two runners have the same engine, the one who uses less energy at race pace usually wins.

Strength training can improve lower limb stiffness, force production, tendon efficiency, coordination and posture under load... Basically you become better at putting force into the ground without wasting as much energy.

That means better stride mechanics, less collapse through the hips and knees, more pop off the floor and less “leakage” with every step

You may not feel dramatically different on day one, but over time, it often translates to a runner who feels lighter, snappier, and more efficient.

2. It helps you hold form when fatigue kicks in

A lot of runners don’t really slow down because they lose fitness.

They slow down because they lose shape.

As fatigue builds your hips drop, your knees cave, posture collapses stride length shortens and contact time gets sloppier

Strength training helps you maintain better mechanics when the race actually starts to hurt.

And that matters, because your form in the final third of a race is usually a much better reflection of your true physical preparation than how you look in the first 10 minutes.

3. It can reduce your injury risk

This is the part many runners ignore until they’re already in a moon boot or Googling “why does my shin feel like it’s cracking”.

Running injuries are extremely common. And most of them don’t happen because running is “bad for you”. They happen because the body is being asked to tolerate loads it isn’t well prepared for — repeatedly, at speed, under fatigue, over weeks and months.

Strength training helps build your tolerance to the demands of running by improving the capacity of the muscles tendons and joints to handle the repetitive stress of running.

For runners, thats gold.

Because the best training plan in the world is useless if you’re constantly having to stop and rehab every 8 weeks.

The biggest misconception: “Strength training will make me bulky/slow/tight.

This one needs to die.

Most distance runners are not one gym session away from accidentally turning into a 94kg rugby player. this is not what a smart runner’s strength program can do.

Getting significantly “bulky” requires:

• a high training volume

• a calorie surplus

• enough stimulus to drive muscle growth

• and usually a fairly deliberate intention to build size

And even after such intentional training, many people still fail to bulk. Step into the weights section of your local Virgin active and just witness how many people in there are still scrawny haha.

Good strength work for runners is usually built around:

• lower body strength

• unilateral control

• posterior chain development

• core stiffness

• tendon resilience, and

• a bit of power or plyometric work where appropriate

Done properly, it should make you feel more athletic, not heavy and stiff.

In fact, many runners feel better once they start lifting because their body finally has some structure behind the engine.

If you’re time-poor, here’s the key question

Not all runs are equal.

If your week currently includes a “filler” run — one that’s too easy to drive real adaptation and too hard to count as proper recovery — that is often the perfect candidate to replace with strength training.

That’s the bit runners don’t always want to hear.

Because there’s comfort in logging kilometres. It feels productive.

But if one of your weekly runs is just junk volume, then swapping it for strength work is often a smarter investment.

In many cases, one strength session per week can give you:

• better durability

• better mechanics

• fewer breakdowns, and

• a stronger platform for your key runs

That’s a very good return on time.

So… is it worth it?

If you’re already running at a high level with a very well-structured week, the answer is nuanced.

But for the vast majority of everyday runners?

Yes, absolutely.

If you’re time-poor, strength training is not a distraction from running.

It’s often the thing that helps your running finally move forward.

Because better runners aren’t always the ones doing the most.

They’re often the ones doing the things most others keep neglecting.

And strength training sits very high on that list.

Final word

If you only have a few sessions per week, every one of them needs to earn its place.

A well-designed strength session can often do more for your long-term progress than another average run.

Not because running doesn’t matter.

But because stronger, more robust, more efficient runners usually perform better — and stay in the game longer.

And if your goal is to run well for years, not just survive your next training block, that matters.
