Many years ago I heard that men perform better than women at all distances marathon level or shorter but that women perform better than men at distances greater than a marathon and that it is thought that this might be because women utilize fat better
However I have an alternative theory that women have more free time to practice for ultra marathons because of the way society is structured
Also are there more men beating women's times nowadays
The top 2 winners were a housewife & a man
What is the longest running distance in military competetions?
Do they have competetions with a distance longer than a marathon?
