Multi-day endurance events demand more than a “just get through today” fueling plan. From ultra running and bikepacking to stage races, hiking, and long-distance paddling, learn how to balance carbs, fluids, electrolytes, protein, real food, and recovery so you can come back strong for the next day’s effort.

Leucine, isoleucine, and valine are amino acids better known as branched-chain amino acids (BCAAs). These essential building blocks of protein are unique, and can play a role in fueling, reduced fatigure and soreness, as well as muscle and bone health.

The word “diet,” by its definition, describes any food that a person consumes. A diet of Cheetos and soda is still, by definition, a “diet.” But over the years this word has come to represent the idea of losing weight, and often using some sort of restrictive eating plan.

Osmolality is a measure of the number of dissolved particles in a solution. You can think of it as a fancy word for the concentration, or density, of a fluid. Scientifically speaking, the osmolality of a solution refers to the concentration of osmotically active particles in that solution. Osmolality is a function of the number of particles and is not related to particle weight, size, shape, or charge. Almost every fluid has an osmolality above zero — Except for distilled water, which has been processed to remove all other substances or “solutes” from the water molecules.
