“I’m the luckiest man in the world,” says Larry Macon, a partner in Akin Gump Strauss Hauer & Feld, who nearly completed the Boston Marathon yesterday.

“I was at mile 25, when I was stopped and was told, ‘You can’t go to the finish line,’ ” recalls Macon, whose name has appeared four times in the Guinness Book of World Records for his completion of record-setting numbers of marathons per year — more than 150 in 2012.
