How many people have walked across the US?

While exact numbers are difficult to determine, thousands of individuals have attempted to walk across the United States since the practice became popular in the 19th century. Some notable figures, like journalist and adventurer David Kunst, completed the journey in the 1970s. More recently, various adventurers and charity walkers have undertaken similar treks, contributing to a growing but still relatively small community of cross-country walkers. Overall, the total number of people who have successfully walked across the U.S. is likely in the low thousands.
