Overview
The Muraoka 88 km Ultra Marathon was a road race held in Muraoka, Hyogo Pref., Japan. Featuring 800 meters of total elevation gain over 88 kilometers—amounting to 9.1 meters of climb per kilometer—the paved profile kept the terrain running relatively fast compared to steep mountain events.
Time limits demanded steady management on course. The 14-hour limit required a minimum pace of 9.5 minutes per kilometer, making the cut-off tighter than 81% of 50mi races and more generous than only 19%.
The event drew a substantial turnout for the category, posting a field bigger than 90% of 50mi peers and smaller than 10%, with 218 runners completing the 2025 edition across its 10-edition run.
