Marathon Readiness Series
The 2025 Marathon Readiness Series, presented by Shaka Racing in Honolulu, Hawaii, is a multi-race event designed to prepare runners for the Honolulu Marathon. The series includes four competitive races: the Boca Norman Tamanaha 15K at Kapiolani Park, the Runner's HI 20K at Kalaeloa, and two half marathons—the Uloha Kailua Half Marathon and the Running Room Val Nolasco Half Marathon. A bonus non-competitive longer run will be announced.
Enhancements this year feature porta potties, upgraded custom performance finisher shirts and medals, and a new team/running club category with special awards. The Kailua course returns to Kailua Beach Park, with potential improvements to the 20K route. Visit the organization's website for the most recent information.
