Will women outrun men in ultra-marathon road races from 50 km to 1,000 km? In the literature there are several evidence that women can beat men on the whole long running tracks. We went to this question and have collected and evaluated for 50 km, 100 km, 200 km and 1000 km all the rides of the world from the period from 1969 to 2012. Over the years, the fastest runners were over 50 km and 100 km more and faster, while the fastest runners scored over 200 km and 1000 km no improvement.The difference between the fastest women and the fastest men took over 50 km and 100 km, but remained unchanged over 200 km and 1000 km. If one takes the fastest times, then for the four examined routes above 100 km with 5% of the slightest difference was present, over 50 km at 15.4%, on the other hand, the highest difference.
The comparison over the four running routes showed no connection between the difference in the running speed and the running speed, so the women could not approach the ultra-long running tracks not to approach the men or overtake.
