In February of 2015, three runners from the Pacific island of Guam were brought together by the idea to fuse performance athletic apparel with the unique style elements of the Pacific islands. Since then RUNGUAM has transformed the island's running and sportswear scene.

Over the years RUNGUAM has evolved its mission and has grown into hosting various running events focused on social running, competition, and running development. These events include Run With Friends, RUNGUAM Virtual 5-Mile Race, and Discover Speed: Kids Camp.
