For active people, early morning running would be enjoyable. Since Gifu is known as the birthplace of Ms. Naoko Takahashi, a gold medalist in the women's marathon in the 2000 Sydney Olympics, the city built a marathon course named after her on the riverside. For long-distance runners, there are very unique concrete embankment structures called "tatami-tei" on the south side of the riverbank between the Kinka and Chusetsu Bridges. In the event of a flood, neighbors take out their tatami mats and insert them into the slits created on the structures, using tatami mats to block flood water.
