Nyad's previous try was cut short amid boat trouble, storms, unfavorable currents and jellyfish stings that left her face puffy and swollen.
This time, she wore a full bodysuit, gloves, booties and a mask at night, when jellyfish rise to the surface. The new silicone mask caused bruises inside her mouth, making it difficult for her to speak, she told her team as she neared land.
Doctors traveling with Nyad had been worried about her slurred speech and her breathing, but didn't intervene, according to Nyad's website.
"She was incredible to watch the whole way through," said one of her doctors, Derek Covington, speaking with The Associated Press afterward.
Covington said Nyad was given IV fluids on her arrival to combat dehydration and was resting and being checked out at a medical center as a precaution.
