Here you will find necessary information about the race - will be updated continously.


In 2020, the pandemic cancelled the race, which unfortunately was also the case now in 2021. 2022 will be the 3rd try & then we will run damnit!

We closed the application at 150 people as we really believed & hoped that the government would go on FHM's response to easing the restriction ordinance, where they proposed a participant ceiling of 150 people in a high virus spread situation for exercise races outdoors, which would take effect from 11/4.

But yesterday's (March 31) decision from the government & FHM to postpone these reliefs to May 3 (to begin with) gives us no choice but to cancel once again (= postpone again) WINTER BAY Backyard Ultra, because it is still a maximum of 8 people that applies. 

NEW DATE = weekend May 14-15, 2022 (same time, same place, same course).

This means the following:

  • All registered participants will of course keep their starting places = will be automatically transferred to the new date 14-15/5 - 2022!
  • If for any reason you do not want / can not participate in the new date, we offer you a 70% refund of the registration fee.
    • NOTE! This offer is valid until 31/5 - 2021.

We hope of course that you are still eager to run this particular race & want to keep your starting place. Of course, you have the opportunity to sell / transfer your starting place if you later discover that you do not have the opportunity to participate in the new date - for example, we currently have about 25 people on the queue / reserve list.

If you want a refund, we ask you to return with bank + account number and we will arrange the refund of 70% of your registration fee.


WINTER BAY Backyard Ultra is organized by Run Raisers (from Sweden), who also have been organizing KRKA Ultra Challenge in Croatia 2018-2019 (the 2020 & 2021 editions cancelled due to Covid-19).
