This beautiful USATF certified course is all downhill except for a few gently rolling uphill sections at the beginning of the course. During the first 3 miles, the course is through the Volcano Golf subdivision and turns right onto Highway 11 as it passes through Hawai‘i Volcanoes National Park. For the first 18 miles the course is surrounded by a mixture of original Hawaiian hapu‘u & ʻōhiʻa rainforest, residential and agricultural land. The Start on a clear day offers a spectacular view of Hawai‘i’s highest volcanoes, Mauna Loa and Mauna Kea, and during the first few miles runners will experience the dawn chorus of many Hawaiian endemic birds that may include the Apapane, Hawai‘i Amakihi, I‘iwi (all three are Hawaiian Honeycreepers), Oma‘o (Hawaiian Thrush), and Hawai‘i Elepaio (a monarch flycatcher). As you run, keep your eyes open for the Nene (Hawaiian Goose) and the ‘Io (Hawaiian Hawk), both endangered Hawaiian endemic species. After Volcano at Mile 7.67, the race continues downhill along Highway 11 until Mile 26.09 when runners turn left into Herbert Shipman Park with the Finish on the grass field next to the parking lot for the Armory.
