Meb Keflezighi won the U.S. masters half marathon national championship in 1:02:29 at the San Diego Rock ’n’ Roll Half Marathon, . He was second overall, losing to pacer Jordan Chipangama, who edged the win by two seconds.
It was the masters debut for the 2014 Boston Marathon champion. He turned 40 and gained eligibility for the race just last month.
Along the way, Keflezighi set American masters records with his splits at 15K and 10 miles. His time in the half was fast enough to break the masters record for that distance, but the San Diego course has too much elevation drop to be eligible for the record.
