Performance and Age of the Fastest Female and Male 100-km Ultramarathoners Worldwide From 1960 to 2012 We have all existing competition results for 100 km from 1960 to 2012 examined with the idea to find the age of the best performance. Overall, 18,998 women and 129,019 men were identified by the total of 148'017 final times.If you take the top 10 a year, you come to the end that men like women became faster and the women approached men.
It is very special but that both men and women’s age is the age of the best achievement and has not changed over every year. All details on this topic can be found under https://pubmed.ncbi.nlm.nih.gov/24476771/
