We get an open-entry half marathon through Waikiki without Honolulu Marathon's December field size, but the late Diamond Head climb still makes this more than a beach jog. The course is mostly flat until miles 9 to 10, when heat and an estimated 80 meters of total gain start to matter. April typically runs 21 to 28 degrees. Entry is roughly $120, and there is no time limit.

Why we'd pick it
- The 80 m climbing estimate is useful for planning, not a verified pacing number.
- Open · Direct entry — no lottery to lose.
- A non-racing partner gets a real weekend here — 5/5.
- Race day usually sits 21.9–25.9°C, about 37% chance of rain.
The course
The point-to-point course leaves the Duke Kahanamoku statue on Kalakaua Avenue, runs west to Aloha Tower, returns through Waikiki, and saves its real work for Diamond Head Road around miles 9 to 10. The finish sits in Kapiolani Park. Most of the route is flat, but the late climb lands after the sun and humidity have had time to build.
