This is a list of people who have walked across the United States from the east coast to the west coast or vice versa. Walking or running across the United States has long been pursued as a way to bring publicity to social causes.

Max & Zac Prizant

Max and Zac Prizant, 24-year-old identical twins, became the first twins to run across the country upon completion of their 3,000-mile journey from the Golden Gate Bridge to the Brooklyn Bridge to raise money for Covid-19 relief. They started their journey May 21, 2020. The twins crossed the Brooklyn Bridge on New Years Eve of 2020, raising $15,000 for Heart to Heart International's Covid-19 Relief Fund in the process. They conquered myriad obstacles, including: ten charging wild stallions in Dixie Valley, NV; week-long stretches of triple- and single-digit temperatures in Stockton, CA; 800 miles of oncoming traffic along I-80 West, and the incineration of their support vehicle in York, NE (after finding a replacement, the twins completed the last five hundred miles of the journey from Youngstown, OH to Brooklyn, NY by traveling 30+ miles per day from hotel to hotel.) Max and Zac averaged over 26.2 miles on days traveled, covering 62.1 miles (100 km) on their highest volume day through Wyoming's Red Desert. The twins made headlines in Potter, NE and NBC New York. They tracked their journey on Strava.
