The double marathon (52.4 miles)

Run start time is 6:00 a.m. (12 hour limit). The Run start is located about 1 mile from the town of Hawi on the main HWY. Runners bust their quads with an 18 mile descent to the rollers of the Queen K highway, where they will face oppressive heat and torturous lava fields all the way back to the town of Kailua Kona.
