Ready to Swim 103 Miles With the Sharks

From the article...

"She will swim about 60 hours in the churning sea, 103 miles across the Straits of Florida from Cuba to Key West. Every hour and a half, she will stop to tread water for a few minutes as she swallows a liquid mixture of predigested protein and eats an occasional bit of banana or dollop of peanut butter. She will most likely hallucinate and endure the stings of countless jellyfish. Along the way, sea salt will swell her tongue to cartoonish proportions and rub her skin raw."
