Warm start, moderate wind

A warm 75°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Moderate winds around 16mph may affect pacing on open sections of the course. Moderate humidity at 76% is worth noting for effort level, especially in later miles.

Race Info

The Ho'omau 5K starts and finishes at Wai Kai, a waterfront recreation facility on Oahu's Leeward coast in Ewa Beach, and runs alongside the Half Marathon and 10K. The fully paved course leaves Wai Kai on Keone'ula Boulevard, turns onto Kapolei Parkway, and turns back to retrace the route to the finish, the shortest of the three out-and-back courses at this venue. Aloha Racing organizes the event.
