Event overview
ÖTILLÖ Casco Bay USA is a swimrun event held in the Casco Bay islands off Portland, Maine. The course uses multiple islands, ocean swims, tide-affected passages, and rocky running terrain. Athletes and volunteers are transported to start islands by Casco Bay Lines ferries; those tickets are included for athletes and volunteers. Spectators must arrange their own island transport. The finish and post-race area is on Peaks Island.

Mandatory athlete-provided gear includes shoes to be worn throughout, a wetsuit, a whistle, a compression bandage, and a tether. Teams must stay together and follow the marked course; littering and missing mandatory gear can lead to disqualification. Post-race food and drink are available near the finish.
