Tao of Running 10-Week Transformation

A Fit Body, A Sharp Mind, A Happy Soul! 

Human Beings Are Supposed To Be Fit, Healthy, Peaceful, Balanced, Focused, And Truly Happy... 

But The Fast-Paced Sedentary Modern World Has Negatively Impacted Our Health, Performance & True Happiness...

We have become really busy and are constantly overwhelmed by responsibilities and unending to-do lists.  As the years go by, we can feel our energy levels as well as physical, mental, and emotional health draining away. This isn't normal and this isn't right. I designed Tao of Running to help people feel like humans at their best again, not just machines waiting to break down. You will know that program is for you if more than a handful of the following statements apply:

  • You find yourself feeling moody and irritable
  • It seems like you're always tired and 'low in energy'
  • The idea of running and jogging seems painfultiring, not really for you
  • You struggle with weight loss and/or improving your overall health?
  • Your last blood test made your doctor frown and/or suggest a healthier lifestyle
  • You tend to get injured easily from exercise 
  • You feel exhaustion instead of exhilaration from exercise and running 
  • You regularly feel nervousanxious, and/or worried?
  • You feel burnt out or even depressed
  • You are exhausted of this continuous tyrannical little voice in your head
  • You feel the need to create some 'space' for yourself
  • You experience brain fog and lack focus/concentration during your day
  • You have difficulties making good decisions, prioritizing your work and delegating
  • You lack creativity and /or intuition
  • You exercise regularly but it does not really help to improve your health and well being
  • You need an activity that you can do anytime, anywhere

According to Daniel Lieberman, chair of the Department of Human Evolutionary Biology at Harvard University and author of the book, "The Story of the Human Body", human beings went through 3 main “cultural revolutions” in the last 10,000 to 15,000 years – which represents less than 1% of the time of the history of human evolution - and our brain and body were not able to adapt and cope biologically with them: 

  •  The Agricultural Revolution 
  • The Industrial Revolution 
  • The Internet / Digital Revolution 

These revolutions have completely changed the way human beings move, think, eat, sleep, live in community, …

More about our evolution ... 

The human body and mind could not biologically cope with these cultural revolutions and it is one of the main root causes of chronic stress, modern diseases, and unhappiness.

Chronic stress is the number 1 killer of our modern world. According to the American Psychological Association, chronic stress is linked to the six leading causes of death: heart disease, cancer, lung ailments, accidents, cirrhosis of the liver, and suicide. And more than 75 percent of all physician office visits are for stress-related ailments and complaints.

But, it does not need to be like this, human beings are supposed to be fit, healthy, peaceful, focused, and truly happy. We can see some “living proofs” of this with the Tarahumara community. The Tarahumaras are a tribe of Indians hidden in Mexico, Copper Canyon. They have never been exposed to our modern world practices and they have had an unchanged lifestyle for ages.

  • They are not violent and they do not fight. They never entered into any conflict with the conquistadors. They hid in the Copper Canyon where they still live today.
  • They run mega-marathons not marathons. The act of running is part of their daily life and they do it with a sense of freedom and joy a smile printed on their face.
  • They are free from our modern diseases such as cancer, autoimmune diseases, cholesterol, clinical depression, etc...

"Running used to be a painful and energy-draining activity for me. Participating in the Tao of Running program helped me to commit some time/energy to do something and change the status quo.The innovative Tao approach to running made me change gradually my perceptions and my feelings about running. My runs became more pleasant, more relaxing and my capacity to run longer distances has increased throughout the program.Now, I do feel more motivated, healthy and I have a sense of "inner satisfaction" after each long run. Otherwise, Tao of Running provided me insights and techniques applicable in my everyday life to increase my well-being in general."

Michael Benamar
Global Segment Manager - Charles River Laboratories

“The 10-week transformation program has delivered much more than expected.I had several “a-ha” moments over the weeks and it has provided access to a huge amount of information summarized logically, presented in a fun and user-friendly manner. It is like 3 entire courses about running, mindfulness, and nutrition and how they relate to each other rolled into one!For example, it allowed me to change a long-held mindset of 'all or nothing'. I run now 3 or 4 times a week without strain. I have more clarity, focus and I am better able to observe my thoughts, feelings, and actions. I have also increased my ability of body awareness/sensing in the present moment.I highly recommend this holistic and transformative program!”

Nadene Tensen

"I ran my first half marathon in 2010. I enjoyed the 2.5 hours but my whole body ached for a few days after! Even though I subsequently went on to do a few runs (10 – 15 km), I never really felt motivated to run vs going to the gym for my Body Combat/ Yoga/ Dance classes.Fast forward 5 years later, I am now a very busy full-time working mum of 2 kids. I no longer have the luxury of time to travel to my gym as often as before. I wanted to look for a sport activity that I can do anywhere, and whenever I can find the time. Running seems like the most obvious thing to do. However, I know I must enjoy running if it is going to be sustainable.My 10-week journey had been eye-opening & fun. I learned better techniques to run, and most importantly, running with mindfulness.The end result of most of my runs is that I feel energized, relaxed, and motivated to continue running. My body no longer suffers from post-run muscle aches. I aim to do a few half and train for a full marathon.Stephane will be my go-to coach to help me get there. He had helped me to enjoy running and I believe everyone is indeed born to run !"

"This is not a new year resolution… It's a lifetime resolution!I am 44 yo. And I didn't know how to breathe. I didn't know how to run. I didn't know how to eat. I didn't know how to be at peace with myself. Now I do. I (re)learned it through this great program. Lasting impact on your well-being!Good for your body, your mind, and your soul. Try it and (re)connect with your true self."

Laurent Duvilier
Regional Chief of Communication, Latin America - UNICEF

”I reside in the States and participated in the Tao of Running 10-week program, which changed my life!First of all, Stephane is truly an amazing and accommodating coach. My program ran over the allotted period, due to time constraints and holidays, but Stephane was a dedicated professional and committed to helping me complete his unique program.The program helps with running techniques, nutritional recommendations, lifestyle changes, all to help one live a healthier, happier, and more balanced life.I highly recommend Tao of Running to anyone in any part of the world looking to learn how to enjoy running with its benefits. Stephane is a great motivating coach who will ensure that you reach your personal physical and mental goals. A life-changing program for all fitness levels.”

Mouni Chouban

From 'I HAVE to run' to 'I WANT to run'!"I started to run occasionally almost two years ago when I was in my early 40s and realized that some physical exercise should be good, not only for my body but also for my mind.From a practical perspective, running was the most convenient activity as I could practice it whenever and wherever and could be easily accommodated within my existing (and busy) professional and personal life. However, unlike other types of sports which I used to practice and enjoy, running was an activity that I hated all my life. It became like a sort of a challenge: the more I run the more I hated it.Then, I stopped for a while, but I felt guilty and restarted again, but again I stopped, restarted, stopped… Then, by coincidence, I came across Tao of Running.Stephane is a passionate trainer and teacher. His knowledge and his background are amazingly broad and his statements and pieces of advice are deeply supported. Through his coaching sessions, I progressively started to feel what he was telling in the 'classes' was not any more theory but real.Following Stephane's techniques and mindfulness advice I've started to run smoothly, wisely, aware of my physical sensations, then the overall benefits flew naturally.Personally, I am feeling healthier, with more confidence as my physical condition has improved; it has also impacted positively my professional life as my levels of stress have decreased and mindfulness has helped to analyze obstacles and behaviors from a different perspective, resulting in better overall performance."

Ana Alvarez
Business Development Director Malaysia - Airbus

After 10 Week Transformation Program in 2015:"Tao of Running is an astonishing & original approach. It is more focused on learning/experiencing feelings and understanding oneself.Stephane is passionate. He communicates his enthusiasm in a cheerful manner that makes the coaching sessions very comfortable.Stephane managed to create a very original program that allows people from all backgrounds to feel how running can become rewarding without pain.This is not theory, this is a living experience combining very interesting techniques and psychological approaches to encompass sport under a new angle, to feel one's body."

Loïc Martineau

"I had major surgery a few months before starting the Tao of Running program. I wanted to improve my techniques to be able to use running as a way to come back in better shape.With Tao of Running, I learned the way to run without stressing my body. It has now become a habit that I practice on average 3 or 4 times a week and I feel fitter, more energized and I have started losing weight."

Deborah Whitehead
Business owner

"I thought I had signed up for a running coaching program but I received so much more than that. Stephane presents a holistic approach to improving one's lifestyle through his Tao of Running transformation.And a transformation program it is! He does not only advise on proper running techniques, but he also offers a complete toolset to develop healthy habits with nutrition, mindfulness, etc.The results are quick to show: I enjoy running regularly again despite previous injuries to both knees, the quality of my sleep has improved and the occurrences of my migraines have reduced significantly. Add some weight loss to that and joining Stephane's coaching has been the best investment for me last year.I highly recommend it to anyone who wishes betterment in their lifestyle."

Nathalie Richez

"A few months ago, I was diagnosed with lung disease. I was new to running and ready to give up. But I was already addicted to this sport and I wanted to persevere.Thanks to my meeting with Stéphane, and through the program Tao of Running, I was able to move beyond my illness... Each module of the program was a step towards my new balance... running techniques, breathing, mindfulness, serenity, acceptance, and resilience...Today, I practice running several times a week with a lot of fun! Stephane accompanied me step by step to find my own pace, my own "running style", and I cannot thank him enough for that. Tao of Running is a fantastic program created by a fantastic coach! Thank you Stephane !"

Frequently Asked Questions

Question 1: Is this a running program ?  NO!

Of course, You will learn running form and techniques to run efficiently and avoid injuries. It is part of the program. But, it is MORE THAN THAT. This is only a means to an end NOT the aim of this program.

With this program, you are accompanied for 10 weeks to take better responsibility for your life. It provides various mind-body strategies, techniques, and tools that you learn to apply inside your running practice to rewire your brain and re-balance your nervous system. 

This leads to the various outcomes of improved health, fitness, feeling more in harmony, more balanced, and confidence to navigate with resilience in our highly unpredictable fast-paced modern world.

Last but not least, you develop new habits and routines during the 10-week duration that at the end they become an entire part of your lifestyle. That is why we can say that this is a mind-body transformation through running.

Question 2: I'm soooo busy 😩. How do you want me to do this for 10 weeks 🙄?

I agree with you, time is a limited resource and we all have only 24 hours per day. This program will take you about 2 to 2.5 hours per week for your running practice [3 times a week for 30 min to 45 min] and about 1 hour per week of mind training practice [only after the 4th week].

So, in total it will take about 3.5 hours per week. If we do basic calculations, we have a total of 168 hours in a week [24 X 7 = 168 hours]. 3.5 hours per week is not even 2.5 % of this total time.

Another consideration, time is a scarce resource but what you do with your time depends on your ATTENTION to make the best of your AVAILABLE TIME. And… this program will help you to: Train your attention to be able to make better usage of your time during your day while collecting the health and wellbeing benefits of moving your body. Enjoying the process will be the cherry on the cake !

That is all the beauty of this program. When you will master the tools and techniques, you will hit 2 birds with 1 stone. You will collect the benefits of the movement of your body WITH the benefits of rejuvenating your mind at the same time. The time you will spend will be regained a few times by the benefits you will gain from the practice. You will start 1) sleeping better, 2) have more and more stable energy, 3) manage your stress better, 4) increase your intuition, 5) be less distracted, 6) have more creative ideas, more perspectives to solve problems, and so on…

Question 3: How are you different than other health and performance coaches out there?

According to the Tao philosophy and many other pearls of traditional wisdom, everything is inter-connected. This is valid at a human being level as well. The way you exercise, the way you breathe, how you sleep, what and how you eat, the way you use your brain, and so on... everything is inter-related. One of the key strengths of this approach is that it helps each participant to connect the dots to balance the different pillars and avoid/reduce "internal frictions".

Stephane has iteratively built this transformative approach over more than 20 years of a personal quest to create his own bridges and connect the dots of his life to improve his own health and well-being [you can read his story for additional details]. The strategies and tools are backed by science, and, Stephane has developed skills - most of them certified-  in many areas of health, performance, and wellbeing like running, NLP, mindfulness, nutrition science, the science of endurance mastery, the sleep science, the science of breathing, the science of happiness, neuroscience, change management... You can see read about his credential in Stephane's profile

That is why he is well placed to guide participants on how to create these bridges and to interrelate and align the different pillars to reinforce the transformation effect.

Along with the program, the participants incrementally find in their inner resources how to balance better their life to move the needles of fitness, health, brain performance, and well-being in the right direction for their specific needs.

Question 4: Is this program open to beginners? I am a complete novice. Yes it is! 🙂

The program is not focused on performance but on improving health/well-being through the practice of running first. Each participant will have a different level of fitness and experience related to running, meditation/mind training techniques, breathing techniques, nutrition and sleep sciences, and so on.

The program focuses on providing tools and techniques to better listen to the body and connect body and mind to progress at the right pace based on the level of fitness of each participant.

By enjoying the practice, it motivates the practitioners to do more of it and the performance becomes a natural outcome of the regular practice.

Some participants have never run in their life and might start by mixing walking and running at the beginning. Other participants have already run [half-full] marathon(s) and want to enjoy more their runs, prevent injuries, be less tired, have more efficient running techniques. 

Question 5: Can you tell me more about how the program works during the 10 weeks?

The Tao of Running Transformation program is a 10-week journey towards elevating your fitness, health, mental performance, and overall well-being. During 10 weeks (can be adjusted for a 1 on 1 program), you will experience a fulfilling sense of incremental progress towards your specific goals.

During that period, you will:

  • Take part in 7 training and coaching sessions (2 to 2.5 hours per session mixing theory and “on the run coaching”). In between the sessions, you will receive guidance on how to practice on your own (usually 3 times a week) to build the knowledge into your mind-body and transform it into skills.
  • Have the key slides of the training material for the 7 modules in a PDF format.
  • Have regular interactions with the ToR Coach to share your challenges and progress and receive additional reading material, videos and apps for additional facts & details about the science behind the program.
  • Have a set of coaching cards to support the personal practice and the 10 Week Transformation Program logbook to support the personal practice.
  • Receive a video montage to provide feedback on posture and running form and summarize remaining opportunities of improvement at the end of the program.
  • Be invited to the weekly group run in which all the old and new participants since the creation of the program in 2015 are invited to join (You will continue to be invited to this weekly run after the end of the program).

By the end of the program, you will have initiated the transformation and will experience an increased fitness, health, sense of balance and well-being to motivate you to continue in this direction. It will become an entirely new lifestyle!

Question 6: How can you say if this program will work for me?

Everyone will find something different and will move out of this adventure with a different outcome. But surely everyone will have gained something they will value for the rest of their lives.

More than 250 participants with their different and unique profiles... men or women, young or "older", with or without a job, with or without a position of responsibility, sick or in good health, seasoned runners or perfect beginners, cartesian or mystics, father or mother, single without children,... will answer that question by themselves with a unique testimony of the impact that they got from this program.

The numerous testimonials given during these last 7 years [you can read some in the praise section] can give you a good flavor of the effectiveness of this program.
