A Runner's World article about the research says:
Lead author Duck-chul Lee, Ph.D., of Iowa State University, says that runners who run less than an hour per week gain the same mortality benefits as those who run more than three hours a week.
"Since time is one of the strongest barriers to participate in physical activity, the study may motivate more people to start running,” Lee said in a press release accompanying the research. “Running may be a better exercise option than more moderate intensity exercise since it produces similar, if not greater, mortality benefits in 5 to 10 minutes compared to 15 to 20 minutes of moderate intensity activity.”
