FILE - In this April 21, 2014, file photo, Meb Keflezighi, of San Diego, becomes emotional after winning the 118th Boston Marathon in Boston. Keflezighi was born in Eritrea, but his family fled the Horn of Africa's war and poverty and eventually settled in San Diego. A U.S. citizen, he was a high school standout who went on to break records at UCLA and win four NCAA titles before turning pro in 1998. Keflezighi said he'll hang up his racing shoes for good after running the April 17, 2017, Boston Marathon and the TCS New York City Marathon in November. (AP Photo/Elise Amendola, File)
