Gebrselassie's won all eight half-marathons he's entered, including the 2001 world half-marathon championship in Bristol, England.
"I'm so happy to run my first half-marathon in the Big Apple next month," Gebrselassie said on Tuesday while training in Ethiopia. "I'm sure I will like the race and the atmosphere. Who knows which races in New York might follow in the future?"
Gebrselassie, who won four world titles at 10,000 meters, has also won three marathons.
