A course that goes around Haruna Umebayashi and Misato Umebayashi in Takasaki City, which is a famous place for plum blossoms in Gunma. Although the height difference is a little severe, the plum grove itself is not so far away and I was able to run quite comfortably.
First, from Takasaki Station, go to Ueno Kuniichisha Yawata Hachimangu via Takasaki Shrine. Hachiman Hachimangu is a shrine with a male place where Gunma Hachiman station is also located. After passing Hachiman Hachimangu, head to Haruna Umebayashi. It will be a good climb at the end, but I think that I can go without problems because the distance is not so long. From Haruna Umebayashi to Misato Umebayashi, climb once down the Karasu River. After Misato Plum Grove, Kamitsukeno Haniwanosato Park and then to Takasaki Station again.
