Swimming from Cuba to Florida

At 7.45 p.m. ET on Sunday, 61-year-old Diana Nyad began swimming the 103 miles between Cuba and Florida. 

According to the story on CNN, it will take her close to 60 hours to complete her journey. 

Plugging all of these numbers into Wolfram|Alpha gives some great data. We typed in “swimming female 60 hours,” and left the body-weight to its default, because it is never polite to guess a lady’s weight.   


Throughout her swim she will burn 36,349 calories, 10 pounds of fat, and go through 1920 gallons of oxygen! We got exhausted just typing this Tumblr post up, and she is swimming 103 miles…

Good luck, Diana! To burn the equivalent amount of calories, we will be ice fishing for 252 hours!
