Runners follow an out-and-back loop course that winds along the trails just off the Oahu shoreline at the Gunstock Trails Half Marathon, with the start and finish lines near the Gunstock Ranch, a working ranch situated near the base of the Ko’olau Mountains just off Oahu’s North Shore. From there, the course winds through tree-covered trails as well as open meadows, along the edges of the Hawaii campus of Brigham Young University and back again.
