Banding together as the Achilles Freedom Team of Wounded Veterans, 25 vets took on 26.2 miles.
The group competed in the Honda L.A. Marathon Sunday in Los Angeles through Achilles International. The nonprofit, which empowers people with disabilities to participate in athletics, has chapters across the United States and in 60 countries worldwide.
Achilles International founder Dick Traum, who lost one of his legs at 24 when it was smashed between two cars, went on to become the first amputee to finish a marathon when he crossed the line in New York in 1976.
The Freedom Team was founded in 2004 to specifically aid veterans.
"We're giving people an opportunity to achieve," Traum told The Huffington Post in August. "When one achieves it sets off the 'Well, if I can do this, I can probably do that too' response. It improves the level of aspiration."
