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, just across the street from Sacred Heart Catholic Church. 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, finishing at the Old Airport park pavilion #1.

The double-marathon run for Day 3 starts promptly at 06:00 am, on the Mahukona-Niulii Road (Hwy 270), directly across from Sacred Heart Catholic Church in Hawi. Crews will drop their athletes at the start line and then move their vehicles West down the road away from the start to avoid congestion and disturbing the locals. The first mile of the run is a “no-feed” zone, where no crew vehicle will be allowed to stop for their athletes.
