Natural Running Technique : Analysis

After attending Tina Dubois’ session, getting my posture analyzed and spending some time discussing with the Canadian coach about the technique, its applications and her vision as a trainer in barefoot / minimalist running, I gave a great deal of thought to the topic of running form.

Above and beyond everything, I have grown convinced that the act of running is somehow imprinted in our genes because it has played such an extensive role in our evolution. In our modern days, our lack of the need for running, coupled with an increased sedentarity and the use of padded shoes, has blurred that memory, so much so that we “forgot” how to do it.

But more than everything, I think the reason why we forgot it so extensively, with great consequences on our bodies, is our separation from the true source of healthy running: pure, unbridled, genuine fun.

Any kid under 5 or 6 years old stands as a living proof of what I’m saying. Cut them loose in a park on a nice day and watch them go; they’ll start running instinctively, naturally and without giving it a second thought. They’ll chase pigeons, race each other to see who’s fastest or drive the dog crazy. Look at them, too. They take short, rapid steps, close to their center of gravity, it’s true. But most of all, they smile and laugh and cheer and spin themselves silly. And then, they do it again.

Have you ever seen a kid, under such circumstances, turn around and ask: “Mommy, am I running right?” or “How’s my cadence?” or “Is this a good pace?”. Of course, you and I are not five-year-olds. But I have grown convinced that, maybe, we should be a little more like them.

In my small experience as a holistic runner, many people have come to see me and asked for my opinion on their form, their results or their training plans. That typical runner is anxious, self-doubting and immersed in numbers, from their training speeds to the amount of calories they ingest. Could it be that their greatest problem is the absence of fun? Why does running have to be so complicated? Why are we so obsessed about training, performance, plans and strategies?

With that perspective in mind, this brings me to what I liked about Lee Saxby’s Natural Running Technique: the natural bit. Take your shoes off. Jump in place a little bit. See how that feels? That’s how running should feel on your feet, too. Play a song at 180 beats per minute, or listen to a metronome and skip or jump from one foot to the other, following the beat. See how that feels? That’s about how quickly your legs should move, too, when you’re running. Add a little back kick to that last exercise and alternate legs while doing it. That movement? It’s what your back leg should do when you run.

Repeat each exercise a couple of times, and make sure to come back to these exercises every once in a while. They “teach” your body, by way of feedback, on how running should feel. So is rope-skipping, skateboarding (can’t push a skateboard from your heel, now, can you?), walking with stuff balancing on your head and climbing stairs, by the way.

The rest? Act like a five-year-old. Don’t run when you’re sore. Play other games. Develop an aversion for always doing the same thing. Get your friends to join you. Make new ones, too, when you go out to play. Drive a dog crazy. Smile. Breathe. Enjoy.

In my humble opinion, running doesn’t have to be more complicated than that. If you have all of the above basics right and still get injured, I bet my ugliest red Hawaiian shirt that it has to do less about running 178 BPM instead of 180 and more with one of the following:

  • You ran too much, too soon, wanting fast results
  • You overtrained because you had “lagged back” the past couple days
  • You blindly followed a “training plan”
  • You ran when you were sore or despite some pains, hoping to gain from your extra effort
  • You didn’t allow yourself to rest because you thought you’d “lose your fitness”
  • You never take it easy, always running hard
  • You steadily run every day or every other day, no matter what

This is where I beg to differ from Lee Saxby’s technique. I am convinced no two bodies are the same and that any movement has to be somewhat adapted to “how we’re built” individually. The best judge for doing that adaptation is YOU. This applies from yoga to guitar-playing and, in my opinion, includes running. No matter what, if you apply a technique and don’t include your own body feedback in the balance, and eventually the adjustments that come with it, you’ll get injured.

I’m not sure calling some aspects of the running form “injurious” or “incorrect”, without looking at the runner, talking with them about their background, goals and injury history, is the right way to go. It only increases the feeling of inadequacy in the runner and takes away their responsibility in interpreting their body feedback and learning from their own experience.

With that said, I think there’s a lot to learn from the Lee Saxby method. The easy exercises, their natural simplicity and the use of the bio-feedback are very powerful learning tools and cleverly presented so the runner becomes quickly autonomous in their evolution. Coming back to those exercises is also the best advice anyone can get, because it teaches your body over and over again the proper way to move and feel while running.

In my opinion, any runner can benefit from exploring the Natural Running Technique. Watching themselves run on video, meeting other runners and talking about their technique, practicing simple, effective exercises to get or increase bio-feedback and body memory, these are all sound things for anyone wanting to improve their running, stay healthy and injury-free.

Coach Tina has helped me analyze the way I run and she showed me very simple ways of teaching myself and others the basics of natural running. She reminded me that it’s important to get back to these simple things every once in a while, just to make sure I don’t stray too far from the feedback of good body habits.

For the rest, I apply my own simple rule: run like a five-year-old. Smile. Breathe. Enjoy.

The Natural Running Technique



In this second article of the series, we introduce you to Lee Saxby’s barefoot running technique, or Natural Running. The following explanations and graphics come from the coaching material and a live session with Canadian coach Tina Dubois.


What is Natural Running?
According to the method, “Running” is one of the three biomechanical forms of human locomotion, along with walking and sprinting. As you can see, “Jogging” is not a part of the picture here, and is described as an incorrect – an injurious – movement, only made possible because of standard shoes and their lack of proprioceptive feedback.


What’s the technique?
According to Saxby, there is an ideal way for running, and it applies to everyone. It’s composed of three parts; posture, rhythm and relax.



  • Posture means an upright torso with a straight, aligned head. Legs fall under the body, on the ball of the foot… nothing exotic here, except when you look in closer detail. The upright posture doesn’t include the usual “forward slant”, or bend at the ankles, that other methods (such as “Chi Running”) recommend. The foot fall has to be very precise, too, as landing on the side of your forefoot is deemed incorrect. The logic behind this is that your strongest metatarsal bone is, by far, the one leading to your big toe.
  • Rhythm means your cadence is precisely 180 beats per minute. Each of your feet will lift from the ground 90 times each minute, which leads to a very fast cadence. Add in the upright position and the first couple minutes will make you feel like running in place.
  • Relax means no tension in the upper or lower body. Movement is controlled, but not stiff. There is no bobbing of the head or rotation in the shoulders, but nothing has to be held too tight.


Real-Life Example
While at Tina Dubois’ coaching session, she took videos of my running, before and after applying Saxby’s method. For the sake of context, I am a self-taught barefoot runner with a 3-year base, who enjoys mostly injury-free running over all sorts of terrains and distances.


Video 1 : Before




Verdict : Head-Chasing, Forefoot Striking Overstrider
My standard posture, it turns out, is not quite perfect according to this method. Admittedly, the head-chasing part is mostly due to my watching the treadmill console, so we won’t pay much attention to that one and blame it on environmental factors. The overstriding, however, is the money shot. I tend to land on the side of my forefoot, a slight bit in front of my center of gravity. This causes an unbalance and makes me stretch my back leg (called “trail leg”) further behind me.





In Tina’s words :
  • Posture – Pretty good, only slightly bent at the waist (probably because your overstride is also quite slight). I can tell that your head is bent forward mostly because you're looking at the treadmill console)
  • Trail Leg – A little long (indicated by the orange line between your knees)
  • Foot Posture - Lateral forefoot with both feet (more lateral on your left than your right)
  • Overstride – Short overstride (indicated by blue arrow between heel and green line)
  • Rhymth – VERY close to 180 BPM
  • Contact time – 16 frames for both feet (filmed at 60 frames/second) for a contact time of just over 250 ms.

Corrective measures
Where Lee Saxby’s method really shines, in my opinion, is in the corrective exercises it proposes. Nothing complicated here, only a couple routines you can do anywhere, with minimal equipment. here’s a quick rundown :

  • Barefoot jumping
    Jump in place with both feet to a 180BPM rhythm. This will force very quick cadence and instil the feeling of the right footfall, as it is biomechanically impossible to land anywhere else than the ball of your foot. “Remember” the feeling in your feet and reapply to your running.

  • Barefoot walking
    While holding a bar overhead (a broom stick or, ideally, something a tad heavier like a weightlifting bar), walk around barefoot without pressing the bar forward or pulling it back. This forces the upright posture recommended in the method.

  • The "1-2-Pull"
    Same idea as the barefoot jump, this one is practiced on alternating legs, while in place or moving. To a 180 BPM rhythm, fold each knee back once, then “kick” once, higher. Repeat, while staying in the beat.

  • Squatting
    With a straight back, squat down with your whole foot touching the ground. Don’t lift your heels and concentrate your weight on the ball of the foot. You can ensure you have a straight posture by doing this exercise while extending out your arms and balancing a weighed bar on your collarbone.


Corrective measures applied to my… case
Since I have a tendency to slant forward slightly, Tina recommends the barefoot walking exercise. She also insists on my increasing my cadence to 180BPM, using the barefoot jumping exercise and a “metronome” MP3 that I can listen to while training. Last but not least, to take care of my lagging trail leg, she recommends I run stretches while performing the 1-2-Pull exercise. The second video below illustrates both my modified running technique and the 1-2-Pull exercise (notice the “kicking” leg).


Video 2 : After



Verdict : Natural Runner (!!!)
Although my second posture assessment was made easier by having a metronome beat to run to, I have to admit I didn’t put much effort into “trying” to look the part. I think this is largely due to the pertinence of the exercises, which are both simple to master and easy to practice.





In Tina's words :

  • Posture - Perfectly upright (indicated by the back of your ear being on the green line above your centre of gravity and no exaggerated curve in your low back)
  • Trail Leg - Close, which is perfect!
  • Foot Posture - Medial forefoot on the right and a little lateral on the left
  • Overstride – No overstride at all!
  • Rhythm – Right on 180 BPM (determined by listening to the metronome on the original movie file)
  • Contact time – 15 frames, which is perfect!

So in less than 3 hours, under the supervision of Tina, I was able to go from my "standard" posture to a "natural running" form. It required only a couple focused exercises and getting used to a 180 BPM rythm, which felt too fast for comfort but turned out to be close to what I was doing already.


Video 3 : Before + After, a side-by-side analysis



For a somewhat experienced barefoot / minimal runner like myself, adjusting to the Natural Running method was quite a breeze. It seemed like the technique was more difficult to apply for some other "shod" runners attending the session. However, they were probably lacking strength in the stabilizer muscles and had no prior experience of the "barefoot feel", which made listening to their body likely harder. My guess is most of them probably needed only to perform the exercises a couple more times for the posture and the technique to feel more natural.


The next article in the series will be my analysis of the method and what I took away from it, both in theory and practice. As mentioned earlier, I’m inviting you to take part in the conversation in the comments section below. Tina will be there to answer your questions and discuss your feedback.
