Atlantic Crossing on a SUP
6,000 Kilometers by SUP – An Ocean Challenge
5,000 kilocalories per day to maintain the strength
One man, one board, one ocean: Michael Walther is embarking on an expedition as adventurous as it is symbolic. With a nearly six-meter offshore stand-up paddleboard, he plans to cross the Atlantic. Around 6,000 kilometers lie between the Portuguese coast and his destination in Cayenne, French Guiana. Three months at sea, 2,500 hours of solitude, facing calms and storms, scorching sun and cool nights – the project, called Ocean Crossing and part of the “Zero Emissions” initiative, represents not only a test of human endurance but also a statement about the urgency of climate protection and sustainable action.
Nutrition is a decisive factor
Such an endeavor requires more than courage and stamina. Nutrition is a decisive factor, with Walther needing about 5,000 kilocalories per day to maintain the strength for relentless paddling. Over the course of the voyage, that amounts to roughly 600,000 kilocalories – a logistical challenge on such a small vessel.
Here, support comes from BERTRAND. The company’s drinkable meals, usually a practical and healthy alternative for everyday life, will now serve as an essential companion at sea. The principle is simple yet ingenious: a nutrient-rich powder mixed with water becomes a complete shake. Thanks to a desalination system on board, Walther can use the vast supply of seawater to prepare his meals.
The advantages are clear. BERTRAND provides the concentrated energy and essential nutrients required – proteins for muscle maintenance, carbohydrates for immediate power, fats for long-lasting energy, as well as vitamins and minerals to keep the immune system strong. Just as important are the practical benefits: the meals are lightweight, easy to store, require no complicated preparation, and have a long shelf life. Unlike conventional foods, they remain stable for months – a vital factor in the middle of the ocean.
“Ocean Crossing” demonstrates how equipment and nutrition become the silent heroes of such expeditions. While Michael Walther pushes the limits of what is humanly possible, BERTRAND ensures his body and mind endure. The project symbolizes the synergy of sustainability, innovation, and human determination – and shows how, even in the endless vastness of the Atlantic, the right nutrition makes all the difference.
