Race Info
The Akahai Half Marathon starts and finishes at Wai Kai in Ewa Beach on Oahu's Leeward Coast. The course passes Hoakalei Country Club, an Ernie Els-designed course that has hosted the LPGA Lotte Championship, and continues along the coast to Nimitz Beach. Aloha Racing has organized the race since 2023, alongside a 10K and 5K held the same morning. Akahai is Hawaiian for kindness expressed with tenderness, one of five values named in Hawaii's 1986 Aloha Spirit law.
