"A link between scientific rigor and the raw power of life, Pyrène Performance opens the doors to inner exploration."
Pyrène Performance is an independent Toulouse-based nutrition brand dedicated to prolonged endurance. Founded in 2025 by two ultra-endurance enthusiasts, Pyrène Performance was born from the desire to combine science and nature in the world of sports nutrition. We are obsessed with creating products and protocols that allow athletes to no longer compromise between performance and health, for a contemporary and holistic approach to ultra-endurance. We aim to help them pursue their goals by enabling their bodies to perform at their maximum capacity, for extended periods. We believe that ultra-endurance is a journey of the body and a window into the depths of oneself.
Breakthrough innovations for endurance
At Pyrène, innovation is neither a marketing gimmick nor a race for novelty. It is a slow and rigorous quest, rooted in respect for life and human effort. We refuse to choose between the ancestral intuition of the land and the demands of contemporary science. Every formula, every protocol, is born from this fruitful tension between Nature and Knowledge. For us, innovation means listening to the body, understanding the mountains, and designing solutions that enhance performance without ever compromising health. It means seeking the essential, refining the useful, and rejecting the superfluous. It means believing that the future of sport is built on a balance between the long-term timeframe of research and the urgent need to preserve our environment.
Our physical retailers
A new era for gut tolerance and the Athlete Experience
At Pyrène Performance, we have conducted extensive research on sourcing and blending ultra-low glycemic index (DE 10) maltodextrins from rigorously selected European suppliers. This technological choice allows us to offer products that are both highly digestible and boast unparalleled glycemic stability in the world of sports nutrition. By combining these maltodextrins with an optimized fructose ratio, we have formulated products that drastically reduce blood sugar spikes and crashes, while eliminating the often cloying sweetness of competing solutions. Our laboratory and field tests confirm that we now offer the least sweet, most stable, and most tolerable textures on the market – a first for athletes committed to ultra-endurance and prolonged high-intensity activities.
A revolutionary protocol, designed for long distances
Pyrène is the first brand in the world to offer its energy gels in 500ml bottles, allowing for ultra-precise dosing based on each athlete's specific needs. This unique format makes it possible to concentrate all the necessary nutrition for several hours of exertion into a single flask or cycling bottle , eliminating the need to carry multiple individual gels. This protocol significantly reduces the mental burden associated with nutritional strategy in the field: no more counting, planning, or stopping to refuel—everything is already at hand. This approach, designed by and for ultra athletes, redefines the simplicity and effectiveness of nutrition during competition.
Circular Mountains® : A manifesto for sustainable & responsible performance
1. Preserve the long-term health of athletes
Pyrène is committed to formulating healthy, highly digestible products without compromising on nutritional quality. Each ingredient is selected for its tolerance to exertion, metabolic stability, and long-term physiological benefits. Far removed from solutions boosted by refined sugars or additives, we advocate for sustainable performance without putting undue stress on the body.
2. Absolute naturalness and local sourcing
The Label is based on a radical commitment to naturalness: raw materials, without ultra-processing, and sourcing prioritized in the Pyrenees. Our ingredients – mountain sea salt, high-altitude waters, and organic local fruits – embody our deep connection to local natural resources and our desire to preserve their balance.
3. Zero single-use plastics, sustainable protocols
The Circular Mountains® label mandates packaging-free formats compatible with outdoor activities. We design refillable solutions for athletes and race organizers, reducing waste at the source and rethinking the nutritional logistics of sporting events. It's about ecology in practice, not symbolism.
4. Female performance and research on limiting syndromes
Pyrène invests in understanding the specific biological barriers to women's endurance. The label supports research on endometriosis, hormonal imbalances, and PCOS, which are still too often overlooked in the formulation of sports products. Our goal: nutritional solutions designed specifically for women.
