Okayama Marathon 2026

The Okayama Marathon is a major autumn road race held in Okayama Prefecture. It features a full 42.195 km marathon and a 5.6 km Fun Run, both beginning together in the morning. This event ranks among the largest in the Chugoku-Shikoku region, accommodating 15,000 marathon runners and 1,400 Fun Run participants. The marathon is open to registered Japan Association of Athletics Federations runners, general individual entries, and general pairs, while the Fun Run also has individual and pair categories. Both routes commence in front of the Okayama Prefectural General Ground Gymnasium and conclude within JFE Okayama Stadium. The marathon course is certified by the Japan Association of Athletics Federations, and participants must adhere to time limits, with a final cutoff point near the 41.8 km mark. The event's theme, “Run, See, Support,” is evident in its structure: competitive runners can enter the certified marathon, pairs can participate together, and local residents receive priority entry before the general application period. Entry is determined by lottery, reflecting the high demand for a race with more applicants than available spots.
