I have actually been (not) dealing with this injury for three years and have finally gone to the Dr. and have started rehab. Thus I have not been running much in the past three years due to the pain and haven't run at all since last November. This is why Running in Hokkaido has not been updated much.
The Hokkaido Marathon application has started and probably filled up today. The Shiranuka Road Race 10k is done. The Date City Half marathon is coming up soon as is the Honbetsu Park 8k Cross Country. If you like to swim, the Obihiro no Mori Aquathlon is coming up soon in May. Despite my injury I was able to run the Parent - Child 3k at the Shiranuka Road Race this year. I was so proud of my little girl. Check the calendar and Runnet as well. There are many other events in Spring.
