Will women outrun men in ultra-marathon road races from 50 km to 1,000 km? In earlier work, it was speculated that women are able to beat the men on the ultra-long running tracks. We have now analyzed the difference between the genders for the running tracks from 50km to 1000km from the period from 1969 to 2012. It showed that the runners were faster over the years.The women were also closer to men over 50km and 100km, but not over 200km and 1000km.
It is therefore very unlikely that women are faster faster over the next few years than the men. The work can be found under https://pubmed.ncbi.nlm.nih.gov/24616840/
