Out and Back 22 miler

Run with the Pigs

August 14, 2021 @ 6:00 am 2:00 pm

The Maunawili Out-n-Back is a trail run on primarily single-track and jeep road starting near the Ko’olau Golf Course, going to the trailhead in Waimanalo, and returning on the same route. The trail travels in and out of valleys along the Ko’olau mountain range; it is normally very hot, humid, and muddy with rolling hills and frequent stream bed crossings. Aid is provided only at the 11-mile turnaround point, so carrying a minimum of 70 ounces of fluids and supplies is mandatory.


*Only 1 ticket per account is allowed to be purchased.
Registration opens July 26, 2021, at 12:01am.
Deadline to register: August 10, 2021, at 11:30pm.

DOH contact tracers work directly with the confirmed case to identify any close contacts. If through the investigation the contact tracer determines that through your participation in the training run, you might have had close contact with others, you will be asked to contact those people and alert them of your positive test result”
