A Marine veteran said all he was thinking about as he crawled to the finish of the Boston Marathon was the men who died after an attack on their convoy in Afghanistan nine years ago.
Their names were written on his hand, his shoes and his race bib.
They were the inspiration, Micah Herndon said, when he first started running to escape the horrors of war.
Herndon said he never considered giving up even when his legs started giving out about 6km from the end of the race.
"That was the longest 4.2 miles I've ever run in my life," said Herndon, who's from Tallmadge, Ohio.
