It Takes 68 Days to Swim the Full Length of the Mississippi River

On July 4, 2002, marathon swimmer Martin Steel began a journey in northern Minnesota that saw him making his way down the 2,348-mile Mississippi River in an effort to become the first person to swim its entire length. On September 9, he reached his goal, ending up in the Gulf of Mexico in Louisiana after an incredible 68-day journey. That’s about 34.5 miles a day!
