The swimmer arrived sunburned and dazed, and was was put on a stretcher to receive medical treatment, including an IV.
"I am about to swim my last 2 miles in the ocean," Nyad told her 35-member team from the water, according to her website. "This is a lifelong dream of mine and I'm very very glad to be with you."
The support team accompanying her had equipment that generated a faint electrical field around her, which was designed to keep sharks at bay. A boat also dragged a line in the water to help keep her on course.
Nyad's recent swim from Cuba to Florida marked her fifth attempt to complete the approximately 110-mile swim. She tried three times in 2011 and 2012 and once in 1978.
