Running Trails on Kauai
Running trails on Kauai offer a wonderful way to experience the island`s natural beauty while getting in some exercise along the way. Whether you`re an avid runner looking for a challenging workout or just looking to enjoy a leisurely jog through the lush forests and along breathtaking coastlines, Kauai has something to offer for everyone.
One of the most popular running trails on Kauai is the Kalalau Trail, which is also a popular hiking trail. Known for its stunning views of the Pacific Ocean, waterfalls, and lush greenery, the trail offers a challenging yet rewarding experience for those who tackle it. The entire trail is 22 miles round-trip and is best for experienced runners who are comfortable with long, strenuous runs.
For those who prefer a less challenging run, the Koloa Heritage Trail is a great option. This scenic 10-mile trail runs through the historic town of Koloa and takes runners past charming shops, beautiful homes, and historic sites. It`s an easy run that`s perfect for beginners or anyone looking for a leisurely workout.
Another popular trail that`s great for runners is the Wailua River State Park Trail. This 2-mile, easy-moderate trail takes runners through the park`s lush greenery, past streams, and waterfalls, and to the beautiful Wailua Falls. It`s a great option for runners who are looking for a shorter, more scenic run.
If you`re looking for some beautiful coastal views, head to the Maha`ulepu Heritage Trail. This 4-mile trail takes runners along the stunning southern coast of Kauai, offering views of the ocean, cliffs, and beaches along the way. It`s a moderate trail that`s perfect for runners of all levels. When it comes to running on Kauai, it`s important to be prepared for the elements. Make sure to wear sunscreen, bring plenty of water, and wear proper running shoes. Additionally, some of the more challenging trails may require a permit, so be sure to look into that before hitting the trail.
In conclusion, Kauai has an abundance of beautiful running trails for all levels of runners, from the challenging Kalalau Trail to the scenic Koloa Heritage Trail. Whether you`re a seasoned runner or just starting out, there`s something for everyone on the beautiful island of Kauai.
Kauai Marathon
Whether it’s for the challenge, the enjoyment, or the competition, if you’ll be on-island in early September, I hope to see you at the starting line of the Kauai Marathon.
I volunteered during the 2012 race and saw runners ranging from 15 to 80+ years old, mothers pushing baby strollers, and even someone racing in a wheelchair—proof that it’s about the experience as much as anything else. Since its inception in 2009, the race has earned recognition from FlipKey, Runner’s World, and Women’s Running as a top travel and bucket-list destination.
Held in Poipu, the Kauai Marathon offers a 26-mile full marathon and a 13-mile half-marathon, both starting at 6 a.m. Around a thousand participants typically arrive early to beat road closures and grab pre-race selfies. Aid stations line the course—15 for the full, 7 for the half—and you’ll be cheered on by hula dancers, taiko drumming, and the encouragement of the whole community.
Here’s a challenge: the fastest full marathon time is 2:51:45, and the fastest half marathon time is 1:12:35. Think you can beat it?
Koloa Sugar Mill Run
The Koloa Sugar Mill Run is a premier event in Kauai, offering 5k, 10k, and half-marathon distances to suit runners of all levels. The course runs along the bypass road, Ala Kinoiki, and Poipu Road before looping back to the start—mostly flat with a few winding hills, making it accessible for beginners and families alike.
Registration includes a post-race breakfast and a dri-fit t-shirt, with half-marathoners also earning a finisher’s medal. Despite the name, the course doesn’t actually pass through any historical sugar plantation property, but it’s still a great chance to push yourself and celebrate with fellow runners—of all ages, including grandparents keeping pace with the group. Whether you’re experienced or new to racing, it’s a fun, welcoming event worth adding to your Kauai bucket list.

Ultimate Hawaiian Trail Run
More than a race, the Ultimate Hawaiian Trail Run is a chance to move through the breathtaking landscape of Kauaʻi while making a real difference in the community you’re visiting. Open to runners, ruckers, and walkers of all levels, this event winds through the stunning terrain that makes the Garden Isle unlike anywhere else on earth — and every step counts for something bigger.
Proceeds from the event fund free Keala Foundation fitness and wellness programs for Kauaʻi’s keiki (children), providing healthy outlets, strong role models, and supportive spaces that help keep local youth on a positive path. It’s a meaningful way to connect with the island beyond its beaches and trails, and to give back to the people who call it home.
Whether you’re a seasoned trail runner or just looking for an unforgettable way to experience Kauaʻi from the inside out, this event offers community, scenery, and purpose in equal measure. When you race, you help build a healthier Hawaiʻi.
