Three Olympians born in three separate countries are "brothers" and best friends, training together in Flagstaff, Ariz., in preparation for New York City Marathon

Bernard Lagat has never run a marathon but is a five-time Olympian. Abdi Abdirahman is an Olympian who once finished third in New York. Mexico's two-time Olympian Juan Luis Barrios ran a PR in the marathon already this year. The three are best buddies, training partners and sometimes roomies who will run against one another in New York this weekend ... but will still pull for one another.
