Ho'omau 5K, 10K & Half Marathon

The Ho'omau 5K, 10K & Half Marathon takes place in Waipahu, Hawaii, in early May. Runners can choose a half marathon (13.1 miles), a 10K or a 5K, and all three leave in the dark, early hours of the morning: the half marathon at 5:45 a.m., the 10K at 6:00 and the 5K at 6:15.

That early schedule is typical for Oahu, where the day heats up quickly and humidity can be high even in spring. For the half marathon, plan to drink at every opportunity, start steadily and consider a light hat or visor for the sun that arrives soon after the finish. Waipahu is on the island's leeward side, a short drive from Honolulu.
