William Shuttleworth, toting a 25-pound (11-kilogram) backpack and singing "America the Beautiful," departed his hometown of Newburyport, of Massachusetts, on Wednesday for what he estimates will be a 7½-month trek to Vandenberg Air Force Base in Lompoc, California.
"I'm particularly concerned about the number of homeless veterans that have mental health issues and the number of veterans that every day struggle with opioid and alcohol issues," Shuttleworth told WFXT-TV .
He has been walking about 20 miles (32 kilometers) a day for months to train and said he's lucky to be healthy enough for such an endeavor.
The Air Force veteran, who also had a 35-year career as an educator, has mapped his route and plans to walk about 25 miles (40 kilometers) per day. He intends to camp out because he hasn't reserved overnight accommodations.
He estimates he'll go through six or seven pairs of walking shoes.
