What is the age for the fastest ultra-marathon performance in time-limited races from 6 h to 10 days? If you look at the results of individual analyzes of running events of different lengths, it looks like when the top racers are getting older with increasing length of the run. We have analyzed the results of runs between 6 hours and 10 days from the period from 1975-2013.Over the years, the number of successful finishers increased steadily, with about half of the runners have completed an ultramarathon and the other half already two and more runs.Most finishers were in the fourth lifestyle. If all the runners were taken into account for all tracks at the start, the age of the best performance with increasing route length increased, even if only a successful finish or at least five successful finishes per athlete were taken into account.
With increasing number of successful races, performance became better.Over the years, however, the performance decreased while the age of the best mileage increased. In addition, the age of the best mileage rose with the number of successful races. All details under https://link.springer.com/article/10.1007/s11357-014-9715-3
