Kauai Marathon
Race Day Weather
Hot start, moderate wind
A warm 81°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Moderate winds around 12mph may affect pacing on open sections of the course. Moderate humidity at 78% is worth noting for effort level, especially in later miles.

Race Info
The Kauai Marathon and Half Marathon starts and finishes in Poipu, a resort community on Kauai's south shore. The marathon and half marathon share their first 11 miles before the half loops back through Kukui'ula Resort, while the full marathon continues past Lawai and climbs toward Kalaheo before descending back to Poipu. The route passes a stretch of century-old trees known as the Tunnel of Trees and coastal viewpoints above the Pacific. The race is USATF certified. The sold-out 2026 edition was cancelled on September 5, the day before race day, when Hurricane Lowell approached the island; organizers have scheduled the next race for Sunday, September 5, 2027.
