For Staff Sgt. Jose Luis Sanchez, what it means to serve and represent his country is something he knows all too well. According to NBC, Sanchez is a retired Marine who lost the lower part of his left leg by stepping on an IED in Afghanistan in 2011. However, the former military man would not be deterred because of his injury when it came time to run in the 2017 Boston Marathon.

Rather, he showed his pride and honor for his country on Patriots’ Day on an entirely different level.

Sgt. Sanchez wore a Semper Fi Fund shirt and ran on his prosthetic leg while carrying a large American flag for the entire 26.2-mile race, finishing in 5:46:13.

“I want to recognize veterans and everyone who thinks they can’t do something,” Sanchez told Runner’s World. He completed the race as a charity member for the Semper Fi Fund, which supports wounded veterans, Runner’s World reports.
