AIA One Billion Day 2026 continues the mission of the AIA One Billion initiative—aimed at supporting and advancing AIA Group’s commitment to helping over one billion people across the Asia-Pacific region live Healthier, Longer, Better Lives by 2030.This year’s event features the AIA One Billion Trail, a team-based trail running experience pioneered by AIA in Thailand. Designed for teams of four, this unique format reflects AIA’s belief that collaboration is the foundation of success. It’s not just about physical endurance—it’s about building strength together, supporting one another, and sharing the energy and spirit that help us reach a common goal. At AIA, we believe that health is not just personal, it’s collective. And when we move forward together, we move toward a better future for all.
