Kauai Marathon

Poipu, HI
Sunday, September 6, 2026


  4.8 Stars from 5 Reviews

Course Description
The challenging, but scenic, Kaua’i Marathon begins in Poipu, the world-class resort community at the sunny southern end of the island. The marathon and half marathon courses run together for the first 11 miles. The courses follow the contour of the scenic coastline, offering magnificent views of the island’s picturesque beaches, rugged volcanic peaks, and green tropical rain forests. As dawn breaks, runners will experience lush green vistas as they approach the shade of the century old Tunnel of Trees.

The course then winds through misty Omao where the half marathon enters Kukui’ula Resort offering spectacular ocean views for the last few miles. The full marathon heads out to Lawai before climbing to reveal stunning ocean views at the top of Kalaheo.

The remaining miles are a gradual descent until runners receive a rousing island welcome upon their return to Poipu Beach.

Traffic in Kalaheo between Puu and Waha

Full Review:

The traffic control between Puu and Waha feeder roads were not well managed for cars and runners. No or little communication whereby cars were in same lane and head on since no all feeder streets had radio communication thus causing a lot of confusion and potentially dangerous curves for the runners.

Race Tips:

Please have all feeder streets with radio communication.

Travel/Logistics Tips:

Big race organization with local heart

Full Review:

This was my first marathon. I ran in 2012. I used to live in Kauai and traveled for the marathon. A huge part of the island community comes out for the race as either volunteers or spectators or runners. The course is beautiful but challenging. You will probably experience a light shower or two or three. This will be welcome as the climate is tropical and you will be warm running. Locals offer emotional support in the form of cheering, music, and dancing. They also offer snacks and drinks in addition to that provided by aid stations. A banana from a kind family at around mile 15 gave me just what I needed to keep going. A young man in a beach chair along a quiet stretch of Puu Road sat beside his truck and cheered runners going by.

Expo was excellent, course covered tree tunnel, ocean views, mountain views and climbs, scenic local areas and some views of popular hang out spots. Post race hot towel, drinks, and massage were greatly appreciated. The medal was perfect: not too big, not too small, and depicted the race perfectly with the shape of Kauai with a runner over the shape. Still the best and nicest race medal I have ever received and I have run hundreds of races. Kauai and its people are the best. This is a wonderful marathon.

Race Tips:

Expect heat and humidity and rain showers. Expect long steep climbs and rolling hills. Expect breathtaking beauty.

Travel/Logistics Tips:

Make it an experience and stay at race hotel or near start. Sheraton is walking distance from start and finish.

Very well organized from the Expo to the Finish Line. Aid stations every mile for 2nd half of marathon. Few but vocal spectators for 2nd half.

Race Tips:

This is a HOT and HILLY race especially the 2nd half. First 11 miles is run with half marathoners so do not get caught up in their pace. Hydrate early and often.
