Course & Elevation

The Big Island Marathon starts in Hilo on the windward side and travels south along the Kona coast, showcasing Hawaii's volcanic landscape and diverse ecosystems. Runners experience coastal ocean views, lava fields, and the transition from tropical rainforest to drier Kona conditions. The course is relatively fast despite moderate elevation changes, with most of the challenge in the latter miles due to increased heat and sun exposure on the exposed Kona side.
