****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.

For a list of approved suits please go to https://www.teamusa.org/USA-Triathlon/About/Multisport/Competitive-Rules/Approved-Skinsuits. Wetsuits will not be allowed if the water temperature is 84 degrees Fahrenheit or higher.
  • Races will be cancelled if water temperature is 60 degrees Fahrenheit or lower.

  • Lifeguards will be present at several locations along the courses as will support boats/kayaks/stand up paddle boards. All participants MUST wear the provided swim cap.


Both the mile and 400m races are a “deep water” start with swimmers starting in the water just to the right of the boat ramp. The mile swim is a triangular counter-clockwise course. Participants will swim (approximately) towards the Fish, Wildlife and Parks building on the south shore of the lake. They will make a left turn and swim towards the east side of the lake. A final left turn has the swimmers heading west, straight back to the boat ramp. All marker buoys should always be on their left shoulder. The finish line is up the boat ramp through the finishing chute. Swimmers in the 400m race will swim a counter-clockwise route to the first marker buoy and turn around to return to the boat ramp through the finishing chute.

Awards Ceremony

The awards ceremony will begin after the 400 meter race.
