Last years winner, the now-deceased Kelvin Kiptum, ran the course in a world record two hours, 35 seconds. While Cooper probably wont be setting any world records, she has still been training hard for Sundays race. Running has always been my form of self-care. Its taught me that when the going gets tough, the tough get going. I wouldnt want to run 26.2 miles with any other team, she said. RELATED STORY | At 23 weeks pregnant, woman outruns 7,900 others to win half marathonCooper was crowned Miss USA in August as she studies at Stanford.
