The endurance nutrition brand designed to fuel your performance without compromise. Founded by ultra-endurance athlete Conor O'Keeffe, ALTAR was born from a need for something better: an endurance fuel that could support long hours of training without causing digestive discomfort. After years of testing and refining his own nutrition, Conor launched ALTAR to offer athletes a product that meets the unique demands of endurance sports. Our formulas are designed to sustain energy, aid recovery, and optimise performance. ALTAR isn't just about fueling your body - it's about enhancing every session so you can reach your full potential, whether you're running, cycling, climbing, or pushing through any challenge.
