Rob Jones is a true American hero.

Rob Jones' life was forever changed the day he stepped on a landmine in Afghanistan and lost both of his legs, but not in the way you would think.

Since that fateful day in 2010, the 32-year-old Marine Corps veteran from Lovettsville, Virginia, has excelled in ways most people can only dream of—even those with all their limbs. After being honorably discharged in 2011, Jones earned a bronze medal in rowing at the 2012 Paralympics. A year later, he became the only double above the knee amputee to ride a normal bicycle 5,180 miles across America, from Bar Harbor, Maine, to Camp Pendleton, California.

Now Jones has embarked on his biggest challenge yet: 31 marathons in 31 days in 31 different major cities. Why? Because he realizes that being a double amputee and retired from military service does not mean he's no longer capable of serving his country. Because he wants to show other veterans that they're an important part of society, regardless of what they've been through. And if he can raise $1 million for wounded veteran charities along the way? Even better.

"When I trained with the Marine Corps, I joined a brotherhood to make a difference in the world," Jones told The Washington Post. "That plan was altered when I got hurt, but I'm still going to that same spot of having a positive impact on the world. Now I'm just going on a different route."

In a press release, Jones said he hopes to be "an example of a veteran, and a person who, instead of letting their personal tragedy destroy their life, they use that same tragedy to make themselves better."

Now that's a true hero.

Jones is expected to complete his 31st marathon at the National Mall in Washington, DC, on November 11th. Visit to donate and learn more, like and follow him on Facebook, Twitter, and Instagram at @RobJonesJourney.
