Four-time world champion Cheruiyot, Kitwara line up in Puerto Rico

Four-time world champion Vivian Cheruiyot and the most successful man in the history of the race, Sammy Kitwara, lines up at the 18th World’s Best 10k, an IAAF Gold Label Road Race, in San Juan, Puerto Rico, today.

On-the-comeback-trail Cheruiyot, who gave birth to a boy, Allan Kiprono, last October, makes her maiden road race since her 2012 World Best’s 10k win, where she then became the third-fastest woman in the history of the event.
