A woman believed to be the first person to swim the entire length of the 410-mile Connecticut River will wrap up her adventure this weekend.

Kari Kastango, of South Hadley, Massachusetts, will complete the feat on Sunday at the river’s mouth in Old Lyme, Connecticut.

Kastango, who is a Connecticut River Conservancy board member, has completed the swim in segments–84 distinct outings or swims–since at least 2019.

The longest swim was an 11-mile stretch from Turner Falls, Massachusetts to Sunderland that was aided by a dam release that occurred a few hours before she started. The coldest swim was between Lancaster and Lunenberg this past April (!) when the water was 47.5 degrees. – 10/13 Journal-Opinion
