Faneca said he doesn't miss football but did miss something he did after games.
Faneca celebrated his 26.2-mile accomplishment with an Abita beer at the finish line.
“A lot of people ask me, do I miss football? I don’t miss football but what I do miss is that first beer after a game," he said. "I had the same feeling after the race.”
