****Special Notice****

The Big Sky State Games is monitoring the ongoing concerns regarding the Coronavirus (COVID-19). The health and safety of the participants, friends, family members, the community of Billings and Montana are our top priority. We remain optimistic and hopeful that the Games will be held in July.

With the Big Sky State Games not scheduled to begin until mid-July (some events in June), all events are currently planned to proceed at this time but are subject to change as the situation further develops. Please refer to the Big Sky State Games website for updates.

Registration for the Summer Games will open mid April. The Big Sky State Games is following the recommendations and directives of the Centers for Disease Control & Prevention (CDC) and the state health department/Governor’s Office. We will follow their guidelines in terms of the continuation of events. Should they mandate events be canceled or rescheduled, Big Sky State Games will provide all participants with more detailed information regarding event rescheduling, cancellation, or refunds.

During these unprecedented times, we understand there is a great deal of uncertainty and concern. We all hope that soon we can return to our active and social lifestyles that for many will include sports and recreation activities including the Big Sky State Games. The immediate focus however, must be on keeping your family safe and helping to stop the spread of the virus.

Thank you for patience and your continued participation in the Games.
