Marine Staff Sgt. Jose Luis Sanchez lost part of his left leg to a roadside bomb in Afghanistan six year ago.

But on Monday, Sanchez completed the Boston Marathon, wearing a “Semper Fi” t-shirt and carrying the American flag.

The Semper Fi Fund supports wounded veterans, and Sanchez told Runner’s World that he was running the marathon as a charity member for the fund.

“I want to recognize veterans and everyone who thinks they can’t do something,” he said.
