A circle with a radius of 3.14 km drawn around the remains of Koriyama-kan✨
The course is a 3.14 km radius circle around Koriyama, the site of Koriyama-kan, the former home of Koriyama Castle, which was the center of the area over 400 years ago.
Since the course is in a basin, it is surrounded by mountains. There are a few ups and downs, but overall the course is flat and easy to draw!
