Kona Marathon

Kailua-Kona, United States of America · Sunday 4 July 2027

RoadFull Marathon

Located on the Big Island of Hawaii, Kailua-Kona sits on the leeward side of the island where the volcanic landscape meets the Pacific Ocean. The town has the feel of an old Hawaiian coastal village, with a slower pace than most mainland communities. The backdrop is dramatic, with dark lava fields and Mauna Kea rising in the distance, while the ocean provides a constant presence. It's a place where you'll notice the heat and humidity, even in July when conditions can feel intense. The course is refreshingly straightforward for those seeking a simpler running experience. It's essentially flat from start to finish with only gentle rolling sections, nothing that demands much tactical thinking about pacing or energy management. Runners will spend most of the race on road surfaces, moving through or along the edges of Kona's quiet neighborhoods and along stretches that take in ocean views. The real challenge here won't be the terrain but rather the heat and sun exposure, which are substantial in Hawaii during summer. What you get is a chance to run a marathon where the landscape is beautiful but doesn't fight you, leaving you to focus entirely on the effort itself.
