About the Kauai Half Marathon
This destination half shares the opening 11 miles with the Kauai Marathon and gives runners a concentrated tour of the island's south shore. The appeal is the setting rather than an easy personal-best course: coastal views, rainforest greens, and a polished resort-area finish make it a memorable race trip.
Course
The race begins in Poipu and follows rolling roads toward the century-old Tunnel of Trees and misty Omao. Half-marathoners then turn into Kukui'ula Resort for ocean views and a gradual descent to the Poipu finish. The early climbing rewards controlled pacing.
Race-day weather
Expect a warm, humid tropical morning even with the early start. Passing showers, direct sun, and changing trade winds are all possible, so effort-based pacing and early hydration matter more than chasing rigid splits.
