Mary Keitany of Kenya, who at age 34 is trying for her third straight victory in New York, has made an audacious move near the halfway point — bolting away from the lead pack to potentially cover the final 13 miles alone.
Elite marathoners usually need other competitors to share the load — both physical and psychological — of setting the pace. They tend to run in packs until the final few miles, when the strongest try to break way. Keitany’s tactics on Sunday were highly unusual.
