Earl Granville is an Army vet who lost the lower half of his left leg to an IED in Afghanistan in 2008. To stay active and in shape, Granville has been competing in long distance races, but alway with a hand bike.

This year Granville challenged himself to run the Boston Marathon the old-fashioned way, on foot, or depending on your perspective, the new-fashioned way, with a prosthetic limb.

As though that weren’t challenge enough, watch Granville crossing the finish line carrying the American flag and his running partner on his back.
