U.S. Olympic sprinter Allyson Felix has smashed a world record once held by track star and "fastest man alive" Usain Bolt, and she did it just 10 months after giving birth, Business Insider reported.
Felix competed at the World Athletics Championships in Doha, Qatar this past weekend where she secured 12 gold medals, effectively beating out fellow Olympian Bolt's record of 11 which has stood since 2013.
