Two record-breaking moments at Sunday's London Marathon

The London Marathon yesterday saw a major record-breaking moment. It was the first time two competitors ran the race in under two hours. Sabastian Sawe of Kenya and Yomif Kejelcha of Ethiopia ran the marathon in 1:59:30 and 1:59:41, respectively. The World's Host Carolyn Beeler talks to David Monti, editor and publisher of Race Results Weekly, about this stunning record.
