Wiltonians Jake Kealy, Karen McDowell, and Jim, Caroline and Kristine O’Brien will be among the more than 200 swimmers making waves to defeat cancer during the 10th annual Swim Across America Greenwich-Stamford Swim on Saturday, June 25.

Nearly 100 land volunteers and boaters will also participate in this year’s event, which will take place at 96 Cummings Point Road in Stamford.

Swim Across America, Inc. is a national nonprofit dedicated to raising money and awareness for cancer research, prevention, and treatment through swimming-related events.

Since its founding in 1987, the organization has raised more than $60 million in the fight against cancer with swims throughout the United States.

In Connecticut, the annual event is an open water swim with half-mile, one-and-a-half-mile, and three-mile options. Proceeds of the fundraising efforts support cancer cell and gene therapy research grants administered by the Alliance for Cancer Gene Therapy (ACGT).

Swimmers, boaters, kayakers, paddle boarders and land volunteers interested in participating in the 10th annual Swim Across America Greenwich-Stamford Swim may register at swimacrossamerica.org/greenwich. A pool swim is also available.
