It always seems like female runners, were slower than male runners. In most world-class sports. Is that right?

In general, this is true. Women tend to be slower than men in world-class sports due to physical differences, such as height and lean muscle mass. In addition, research has shown that female runners have lower VO2 max (a measure of aerobic capacity) than male runners. The gap in running performance is partially offset by a tendency for female athletes to have a higher anaerobic capacity, but overall women typically trail men when it comes to competing in athletic events.
