A circle with a radius of 3.14 km drawn on Okayama Castle✨
Mt. So-zan, which was the center of the region in ancient times. The course forms an equilateral circle with a radius of 3.14 km around this mountain.
The course passes by Okayama Castle and Korakuen Garden, which represent the present-day city of Okayama. The course goes around the plains between the Hyakken River and the Asahi River, and is not very undulating. It’s a great new type of sightseeing, walking, or running course!
