Hawaii Kai Ultra Run - Xtreme 2026
The Hawaii Kai Ultra Run - Xtreme takes place in Honolulu, Hawaii, starting and finishing at Kalama Valley Park. This event offers a wide range of distances for participants to choose from:
- Half Marathon
- 30K
- Marathon
- 50K
- 50 Miles
- 100K
- 100 Miles
The course consists of a 9-mile loop on paved roads. From Kalama Valley Park, participants run toward Sandy Beach on Kealahou Street, heading to a turnaround point at Kalanianaole Highway. The route continues along Hawaii Kai Drive, passing through Kamilo'iki Community Park, Lunalilo Home Road, and Wailua Street. The final section includes a segment on Hahaione Street and Pepeeko Street before returning to Kalama Valley Park.
This is a cupless event intended to reduce environmental impact. Three aid stations are positioned approximately 2.5 miles apart along the loop, providing water, ice, electrolytes, and snacks. Participants must bring their own hydration packs or reusable containers. Public restrooms are accessible at every aid station 24 hours a day.
Registered finishers receive certificates, medals, and stickers. The event serves as a 50 States Marathon Club qualifier. Additionally, completion of the 50-mile, 100K, or 100-mile distances can be used as a qualifier for HURT events, provided the participant selects an official wave start for certified timing.
Transportation to the venue is available via public transit, with a bus stop located directly across from the check-in tent at Kalama Valley Park. Visit the organization's website for the most recent information.
