A solo or relay 10 km (6.2 miles) and 5 km (3.1 miles) and 1 km (0.62 mile) open water swims in Sitka Sound with a water temperature range in the mid 50’s. The 10 km course will start at the Mount Edgecumbe High School ramp on Japonski Island. The course will then take the swimmers north out of Sitka Channel and westward along the Fort Rousseau Causeway State Historic Site and loop back to the Mt. Edgecumbe ramp to finish. A turnaround point and/or alternative course will be available for those swimming the 5 km and 1 km distance. Maximum time allowed on the course is 4 hours.


An Escort kayaker is required for solo swimmers and relays, to enhance safety and navigation. For Swimmers who do not have an escort kayaker with them one will be assigned on a first registered first available basis. We will do our best to make kayaks available, either through rental or on loan from event sponsors.

Swimmers must swim on either the left or the right side of the kayak. NO DRAFTING WILL BE ALLOWED. Drafting is defined as “the carrying of a swimmer by the wake of the escort boat, or another swimmer.” If any team engages in drafting, and a complaint by another team is lodged and upheld, the drafting team will be disqualified.


In the relay swims, each swimmer’s first leg is 30 minutes. Succeeding legs are 15 minutes per person. The duration of the final leg can be adjusted at the discretion of the team captain, if more than 15 minutes long. If a person cannot finish his or her leg, the boat is allowed to keep its motor on only to keep present position for the duration of that swimmer’s portion. If the next swimmer enters the water before the proper time, the team will be disqualified.
