She did it! Sixty-four-year-old endurance swimmer Diana Nyad came ashore in Florida after swimming 110 miles from Cuba. It was Nyad's fourth attempt in the last three years to become the first person to make the swim without a protective shark cage. The last one was thwarted by venomous box jellyfish, but this time she's wearing a custom face mask to protect herself from their stings. The journey took a total of about 80 hours.
