So You Want to Start Running Again?
So You Want to Start Running Again?
If you’re thinking about running again (or for the first time), you’re probably also thinking:
Will my knees tolerate this?
What if I flare something up?
I don’t move like I used to.
As someone who dealt with knee pain for much of my adolescence, I get it. I’ve been there.
These concerns are understandable. They’re also very common, especially after 40 or 50.
The good news?
Your body is likely far more capable than you’ve been led to believe.
I can personally attest to this. I went from having knee pain after nearly every sporting event as a kid to running an ultramarathon in my 30s. Don’t let pain, or the fear of pain, stop you from chasing a goal.
What matters isn’t whether you run again. It’s how you return to it.
Why Running Feels Different This Time
As we get older, a few normal things happen:
We lose strength if we don’t train it…
Recovery takes a little longer…
We’re less exposed to impact in daily life…
None of this means you’re “too old” to run.
It simply means your body needs progressive re-exposure, not a sudden return to old habits. Most running-related flare-ups aren’t caused by running itself, they’re caused by doing too much, too soon after years of deconditioning.
The Biggest Mistake I See
As a physical therapist, the most common mistake I see when people return to running is this:
They start too aggressively, don’t give their body enough time to adapt to the demands of running, get discouraged that it feels hard or something hurts, and stop altogether.
If you really think about what running asks of your body, this makes sense. When you run:
Your heart beats faster
Your lungs move more air
Muscles contract repeatedly and move fluid rapidly
Joints, tendons, and ligaments absorb impact
Your brain has to coordinate and tolerate all of it
Your cardiovascular system often adapts first. Your heart and lungs may feel ready before your knees, hips, or feet are.
When those slower-adapting tissues aren’t given time to catch up, pain often follows. The body works as a system and the whole system needs time to adapt. A smart return respects slower tissue adaptation without avoiding movement altogether.
Do You Need Perfect Form or Special Shoes?
No.
You don’t need:
Perfect biomechanics
Fancy running shoes
Long stretching routines
You do need:
Gradual progression
Planned walk breaks
Time for your body to adapt
Running is a skill your body can relearn, even if it’s been years.
What About Knee Pain?
Despite what you may have heard, research does not show that recreational running automatically damages your knees.
In fact, many runners have lower rates of knee osteoarthritis than sedentary adults. The difference isn’t age, it’s how you train. More specifically, it’s how much you train relative to what your body is currently prepared for.
Your body may not tolerate what it did at 20, and that’s okay. With consistent, progressive training, many people end up feeling stronger and more capable than they did in their younger years.
A Better Way to Start Running Again
If your goal is to run confidently and sustainably, the safest approach includes:
Walk/run intervals
A clear progression timeline
Built-in recovery
Guidelines for what discomfort is normal and what isn’t
That’s exactly why I created a structured plan to take you from not running to completing a 5K, without rushing the process.
