Hapalua - Hawaii's Half Marathon 2027

The Hapalua Half Marathon starts at the Duke Kahanamoku statue on Kalakaua Avenue in Waikiki and heads west along Ala Moana Boulevard to the Aloha Tower turnaround, then returns east through Waikiki. It then climbs up Diamond Head Road (the course's only significant incline, around miles 9-10), turns around at Triangle Park, and descends back to finish in Kapiolani Park. The first eight miles are flat; the Diamond Head loop adds a short sustained climb and downhill in the closing miles.
