The four time Calrsbad 5km winner Gebremeskel will have a special test on Sunday as the world's top road racers; Kenyans Baden Karoki, Cybrian Kotut and Geoffrey Bundi, and Eritrea’s Samson Gebreyohannes will try to break Zersenay Tadese's world record of 58:23. The elite group will be paced by Alex Olotiptip of Kenya, who has run the half marathon in 59:58.
“I’m looking forward to making my debut half marathon in Philadelphia,” Gebremeskel said. “As a Carlsbad 5000 winner, a Rock ‘n ‘Roll half marathon is a great choice for me as I know [the organizers] will bring [strong] opposition and put on a great race. I hope to run fast and look forward to testing myself against the world’s best.”
