Hibiscus Half Marathon, 15K and 5 Miler

Memorial Day weekend in Honolulu opens with runners tracing the Diamond Head shoreline at Kapiʻolani Park, where the Hibiscus Half Marathon offers three distances, half marathon, 15K, and five-mile, all launching before the sun fully clears the volcanic ridge above Waikīkī. The early start times the race precisely to catch the coastline at its most flattering: soft morning light, calm trade winds, and a clear view toward Diamond Head’s crater rim.

The course itself threads along some of Oʻahu’s most photographed shoreline without ever feeling like a tourist route, since Kapiʻolani Park’s broad lawns and mature banyan trees give runners a genuine sense of place rather than a highway shoulder. Multiple distance options mean the event draws a wide range of participants, from serious half-marathon competitors to families tackling the shorter five-mile course together, with age-group awards handed out for each distance separately.

Packet pickup at a nearby Waikīkī resort makes lodging in the neighborhood especially convenient, sparing early risers a long drive before the 5:30 a.m. start. Once the race wraps, the same stretch of coastline offers an easy transition into beach time, a stop at the Honolulu Zoo, or simply a slow walk through the park while the morning is still cool and the crowds have yet to arrive.
