Zach Bonner is “pretty tired,” he says. Instead of attending camp this summer, Zach, 11, decided to walk 668 miles from Atlanta to the nation’s capital, Washington, D.C. Why? Zach hopes to raise awareness about the plight of homeless kids. Zach walked from his home in Tampa, Fla., to Tallahassee. Then, in 2008, he did it again, this time walking from Tallahassee to Atlanta.

Since May, Zach has traveled 12 miles every day in his trusty Adidas shoes. Along the way, he has collected more than 1,000 letters about homeless children. He hopes to give the letters to President Barack Obama. Zach says he wants his walk to make a difference.

More than 1 million children in the United States live in shelters or on the streets. During his pilgrimage, Zach spent 24 hours with a group of homeless children so he could learn the difficulties they face.

Last week, Zach walked the last mile of his long journey. More than 500 supporters, including 300 homeless kids, joined Zach. They marched with him down the National Mall. “It was a long walk,” Zach says, “but it was definitely worth it.”

Zach was inspired to help homeless youth when he participated in a 2005 episode of “Extreme Makeover: Home Edition.” He was also inspired by a movie he saw about Mildred Norman, an activist who promoted world peace by walking 25,000 miles.

Zach is also the founder of the Little Red Wagon Foundation. The purpose of the non-profit is to help needy youths. Through his group, Zach has raised money and donated school supplies. “A lot of homeless youth don’t get the opportunity to succeed in school because they don’t have supplies,” he says.

Zach’s volunteerism has even inspired a Hollywood movie based on his life. “He’s the most extraordinary ordinary kid I’ve ever met,” says Michael Guillen of the Philanthropy Project, who is making the movie. “He has literally and figuratively walked the walk.”

As difficult and tiring as the journey was, Zach won’t be trading in his walking shoes. “When homeless kids get tired of being homeless, they don’t get to quit. So why should I quit when I get tired of walking?”
