There are so many stories about Abdi Abdirahman, the longtime bon vivant of American distance running.
About how he fled Somalia with his family and eventually settled, as a teenager, in Tucson, Ariz. About how he picked up running as a college freshman and found that he had a knack for it. About how he has made five U.S. Olympic teams while emerging as a consistent and joyful presence on the world marathon stage, well into his 40s.
Now, after being considered ageless for nearly a decade, Abdirahman, 45, can see the finish line.
