The Karikachi Summer Road Race in Shintoku.
I just got the application for this today in the mail. Very small local race. The short courses are almost entirely on Shintoku's well known grass running course. The one eigth marathon (5.275km) and quarter marathons (10.549km) take you off of the grass course and out onto country roads lined with summer crops of maybe potatoes or sugar beets. Usually the potatoes are in full bloom and their fragrant smell tries to encourage you to slow down and enjoy.
Date: July 17
Place: Shintoku Sahoro Riverside Park Golf Course
The grass running course goes around the golf course.
Fee: 2000 yen for high school and above, 1000 yen for junior high school and below.
Please see the details of the event below and if you have any questions feel free to comment on this post and I will answer as soon as possible. I'm sorry this is not more details but my wife is in the hospital and I have to take care of the kids.
