Matthew Rizzo of Georgetown and Alex Rizzo from the U.S. Naval Academy join DyeStat editor Doug Binder to discuss becoming the fifth set of U.S.-born brothers to run a sub-four mile. The twins both broke the standard last Saturday at the BU David Hemery Valentine's Invitational in Boston. It was the third time under four minutes for Matthew, the first for Alex, who broke the Midshipmen program record with his 3:58.75.
