Retired Marine Staff Sgt. Jose Luis Sanchez became an inspiration Monday after participating in the 121st Boston Marathon.

Sanchez lost the lower part of his left leg after stepping on an IED in Afghanistan in 2011.

He ran Monday’s 26.2-mile race on a prosthetic leg while carrying an American flag, completing in just under six hours.

The retired Marine ran his first marathon in 2015 in Washington D.C. and ran last year’s Boston Marathon.
