2026 Agenda
ALL ADVENTURE STORIES

Immersion in a Fasting & Trek®

Do you find it difficult to fast even though you know it would be good for you?!

This is why Florian developed a simple solution: setting off with a backpack in a group to trek in the heart of nature.

One might think that during a fast, physical strength would wane, and it wouldn’t be wise, or even possible, to walk all day.
And yet…

The Fasting & Trek® is...

WATER FAST

A physical, mental & digital detox accompanied by a personalized purge.

Trek

Stages of varying difficulty, self-sufficiently, with overnight camping.

NATURE IMMERSION

An ideal natural setting to recharge and take stock of your life.

HYGIENIST PRACTICES

Reconnecting with the elements and discovering the main natural health practices.

UNIQUE CONCEPT

An initiative created by Florian Gomet following the expedition: “La Marche Sans Faim”.

GROUP EXPERIENCE

An unforgettable group experience where, nourished by exchanges, we forget the hunger.

Retreat Program

Between one and two months (depending on the format) before the Fast & Trek, you will receive advice by email to help you prepare, to facilitate the fast and optimize its benefits.

To ensure the trek goes as smoothly as possible, here are some recommendations on the physical and practical level:

  1. During the remaining weeks of preparation, gradually increase your training load in walking or running. Remember that all the endurance efforts you are capable of while eating, you will be able to do while fasting! The key is simply to be in good shape!

  2. At the end of this physical preparation (which will stop one week before D-Day, as it will then be the week of vitalization and dietary reduction), you must have AT MINIMUM completed two fasting outings (with or without a backpack) of X km in the same week. X representing the maximum number of daily kilometers for the format you have chosen. This distance should be reevaluated upwards (consider one flat kilometer for every 100m of elevation gain) if you are training with less elevation gain than announced for the trek.

One week before the fast, you must follow a dietary reduction (non-optional):

During the last week before the trek, the goal is to gradually reduce non-physiological foods for humans (see below) in order to perform an initial cleansing of the body. Without this, your body will have a lot to do during the first three days of the fast, with risks of unpleasant symptoms appearing quickly (headaches, nausea, dizziness, tachycardia, heartburn, cramps, skin rashes, anxiety, etc.) which could compromise the smooth running of the trek. This period of dietary reduction is important to facilitate entering the fast on both physical and psychological levels.

Also reduce your pace during this preparation, rest as much as possible, go for walks in nature, do stretches and conscious breathing.

The dietary reduction program:

D-7
Eliminate all refined and processed industrial products, refined salt, white or brown sugar and other industrial sugars, white bread, sodas, stimulants (tea, coffee, alcohol) as well as oils heated to high temperatures.

D-5
Also eliminate processed meats, meats, and fish. Eat raw or lacto-fermented vegetables, fruits, sprouted seeds, seaweed, a few legumes or whole grains if you feel the need.

D-4
Also eliminate other animal products (eggs, dairy, cheeses, etc.).

D-2
Finally, eliminate legumes, grains, and any products containing them (bread, pasta, rice, …), and nuts/seeds. Consume mainly fruits, vegetables, and greens, raw or in juice form, as desired.

D-1
You are expected the evening before the fast at 6 PM at the welcome location. Except for the Mont Blanc trek, it is possible to have dinner that evening (provided you bring your own food as it is not supplied by the organizer) and wait until the next morning to purge. If you are already fasting that evening, you can take a purge without waiting until the next morning.

Purge the evening before or in the morning around 8 AM

The purge is recommended to facilitate the fast through intestinal emptying and the lymphatic cleansing it triggers. To learn more about this, I suggest you read this article (click the link). If you wish to purge at the beginning, and possibly at the end, of the fast, it is up to you to bring:

  • 100 ml of castor oil, purchase by clicking here
  • 60 g of magnesium sulfate (also called Epsom salt), purchase by clicking here
    I will explain on site how to use them (quantities, protocols, etc.) and which one to choose between the two if you are unsure.
    For those who won’t have the necessary items, purgatives will be offered at a price of 10 €.


Departure around 9 AM

During the fasting days, in addition to walking, various activities may be offered: conscious breathing, mantras, forest bathing, cold baths in rivers and ponds (when available), sun gazing, sunbathing, and sauna (on certain F&T only).

In case of dropout or decision by the organizer (on this subject, read the program charter at the bottom of the page) during the trek, it is the participant’s responsibility to return by their own means (taxi, hitchhiking, etc.). No refund or discount will be granted.

The day and time of return to the welcome location vary depending on the chosen itinerary – see the program.

Unless otherwise stated, food reintroduction is at each individual’s initiative.

Your words after the retreat

"These are magnificent experiences!!! I will never forget this adventure! It brought me so much, much more than I imagined and I think that with time, letting it all settle, it will still make me grow in many ways... My most beautiful fasting experience!'"
Delphine
"I followed my heart when it told me, go on, do it. I had just discovered Florian Gomet's proposal to take a group fasting and walking 30 km per day. Me, who loves food, sometimes compulsive about my raw chocolate, with little fasting experience, I was a bit apprehensive. Will I manage 30 km on an empty stomach... And endure the cold since we are in October and I'm used to the Toulouse climate... I was very surprised not to suffer and to have so much energy. Glad to have followed the recommendations of a well-managed dietary reduction before the trek, my process happened smoothly and I nourished myself with all the beautiful presences that accompanied me on this journey. I drew precious knowledge from it to continue my path and filled my heart with these moments spent together."
Karine
"I want to express my deep gratitude for this week we shared! When we were walking and I heard you tirelessly sharing your years of experience, your hours of research, your feelings and observations, I felt truly lucky, inspired, deeply touched, and fully welcomed on the paths of life."
Ophélie
"Back from the '3 Fs' » cold hunger fatigue « a very beautiful but grueling experience, stopped on the fourth day with about 120 km in the legs, a bit more for Agnes and even more for Luna, a beautiful sharing with very beautiful people in a full nature setting, but frankly I didn't expect so much elevation gain in Haut Beaujolais 😔 Thanks again to Florian Gomet adventurer and organizer of this little initiatory journey 😉 An unforgettable experience to live at least once because you can really make huge efforts without eating and even over several days, my biggest difficulty was the pace, and yes I was the eldest 😱 and these young ones didn't spare me 😤 😂😂😂"
Christian
"Thanks for the hike Flo, you are a super guide and wow the level is high!!! It shows me the path I have left to travel!! Everything was top notch: the group synergy, your knowledge in naturopathy and survival, the discussions with everyone, the waterfall, the bivouac sites, the way you guided us with your open-mindedness. I am super proud of myself for having succeeded and for having listened to my body so I say a big thank you for that!"
Florence
"I felt the whole time, even in the difficulties (and god knows how hard the 5th day was) in absolute trust, trust in life, trust in myself, trust in you, in Hervé and in the group. I am proud and full of gratitude for my body that works so well, and for my heart and soul that dared to open and let themselves be carried with so much trust. To date, it is one of the most beautiful experiences I have had the chance to live after giving birth!"
Ophélie
Ophélie
"First, a big thank you for sending the photos they are magnificent! Regarding our food reintroduction, we think we succeeded, thanks to our little experience and your great advice. We are still on a little cloud following this exploit by all of us!!!.... The emotions continued to 'come out' especially for Jean-Louis, while driving towards Marseille and our musical supports really helped with that! For me, I feel a serenity, a well-being out of the ordinary, may I preserve this state... This is one of the fasting stays that has been the most powerful for both of us, it reached very far in all aspects! We await the sequel... which we wish for in this same state of peace or perhaps better or different in our Mental and our Physical. We are proud to have shared it with you."
Véronique
"If you need a Reset, nothing beats a fast and trek with Florian! He chooses superb locations, his knowledge of the terrain of the different routes, his long experience of fasting give us confidence and the adventure, which may seem difficult at first, is a moment shared by all, rich in emotions. For my part, this is my 3rd one!"
Fabienne
"I was very happy and proud to have lived this experience. It was a first for me, I had some fears but my thirst for inner exploration was greater. So I step out of my comfort zone, Florian takes my hand and guides me, reassures, soothes during the fast and also before in the preparation for the fast, for the equipment as well as for the food reintroduction. All in benevolence, gentleness and Love so a big thank you 🙏 for everything!! My fears flew away, I come out stronger ❤️."
Guillaume
"As during the previous fast and trek, I am savoring the post-trek…. 🥰 … sweetness… slowness… every cell vibrates…. I am so nourished by this total immersion in nature. It's nothing but joy 🥰. Thank you Florian for making us live these mini adventures, thank you for your guidance, your sharing 🙏🏻🥰💗."
Joëlle
"I lived an incredible experience. 6 days of walking without any sensation of hunger. I waited for 6 days for the need to fight against a need to eat and intense fatigue. Yet nothing appeared. It was even 'easy'. Florian's preparation in advance allows you to be ready (even if we doubt it deep down!). Then the Trek is just a pleasure oscillating between discussions about raw food, hobbits, health within an extra group. All punctuated by breaks in magnificent places. Hesitate no more, follow Florian's advice and have confidence in yourself and your body. It's unforgettable and you will come back in a new version of yourself. An upgraded version!"
David
"An unprecedented, extraordinary experience where you find yourself face to face with yourself. Lozère offers an ideal playground with magnificent landscapes. An adventure to live if you want to break down your limiting beliefs. Florian knows how to prepare you before the trek, accompanies you during the walk, and guides you with his advice for food reintroduction. This fast and trek offers a reset for your cells. In case of difficulty, the group spirit helps you move forward and go all the way. In short.... an expedition that transforms you deeply, at the heart of your cells 🙏🥰"
Stephane
"I was very happy to meet you and do my first fast and trek with you and all the very nice participants. I definitely plan to do another fast with you when the opportunity arises. For me, you are a great man who knows how to remain humble, I want to thank you for everything you have given me. All my respect to you I wish you again a beautiful life full of adventures and extremely extraordinary challenges."
Bruno
"There is a before and an after Fast and Trek. In this retreat, we experiment and discover wonderful capacities of the body. After this experience, the field of possibilities expands. I recommend it to everyone."
