Welcome to the Swim Across America - St. Louis Open Water Swim! Since 2016, SAA - St. Louis has raised over $1.6 million for our beneficiary: Siteman Cancer Center. Thank you for your support of cancer care in St. Louis.
Each year we are proud to host over 550 swimmers and hundreds of volunteers, spectators and supporters, as well as Gold Medal Olympians and special guests at our charity event. Thanks to you, our event has been at full capacity the last two years. We are so excited to have you join us for our 9th annual open water swim event on August 24th at our spectacular setting on Alpine Lake!
Whether you are a veteran swimmer, you're looking to do your first open water swim, or if you want to participate virtually to help the cause, we welcome you to help us "Make Waves to Fight Cancer.” Together we are making a real difference!
