XTERRA Gunstock Trails Half Marathon

Course highlights

Runners start the out-and-back course for the race at the Gunstock Ranch, which lies about a mile north of downtown Laie on the Kamehameha Highway, and just west of the Malaekahana State Recreation Area.

From the ranch both races follow the same course for the first mile and a half or so until the split, where those running the half marathon turn left and head south while those running the 5K continue west along the trail.

The next portion of the race continues on eastward and southward, roughly in the direction of the campus of Hawaii’s Brigham Young University.

Once runners make their way down to the southern edge of the campus, they hit the race turnaround point and then start retracing their steps along the route they’ve just run, all the way back northward along the trails nearly all the way back to where they split off from the 5K runners.

Once they make it back, they’ll turn left and follow the trail west again for a brief loop and then back to the northernmost part of the trail they ran earlier in the race, during the mile 1 through mile 3 stretch.
