About Emerald City Apnea Challenge
Emerald City Apnea Challenge (ECAC) is a community-run freediving organization based in Seattle, Washington. We host AIDA freediving competitions for athletes, and events for volunteers, across the Pacific Northwest.
Our depth competitions are held in the open water of Puget Sound at Seacrest Park in West Seattle. Our pool competitions are held at the Snohomish Aquatic Center in Snohomish, WA.
Our competitions follow AIDA freediving rules. Find upcoming competitions and events in the Events section, and follow us on the social media links at the bottom of every page.
