Entry for the Niseko Ski Marathon can be made through the Runnet site. But unfortunately this is only in Japanese.
If you prefer English simply send an email to firstname.lastname@example.org with:
- The race that you wish to enter 30km or 10km
- Male or Female
We will send you a confirmation of your entry and payment for the race can be made when you register the day before or on the day at the race venue.
