XTERRA Gunstock Trails Half Marathon

You’ll love this challenging and scenic run on the trails of a real working ranch. Enjoy spectacular views of Oahu including the North Shore as you navigate rolling hills and forest trails. The half marathon is timed perfectly as a great training run for the Honolulu Marathon in December, or there’s also a fun 5k option if you’re a sprinter, a beginner, or someone who just wants to get some exercise in the fresh air.
