Participation and performance trends in elderly marathoners in four of the world’s largest marathons during 2004–2011 The performance development of elite runners on the marathon line is well examined.On the other hand, numbers are lacking and performance with rather older runners of 75 years and older. Now we have analyzed the numbers of marathon runners 4 of the runs of the, World Marathon Majors’ in Berlin, New York, Chicago and Boston from 2004-2011.This period was chosen because during these years could be found on all competitions usable numbers. The bottom line was that participation in the 5-year old age groups of the runners remained constant over 75 years, whose times were slower and the women could not approach men.
This rather unexpected result should be back to the relatively short period of time. The whole evaluation can be found under https://springerplus.springeropen.com/articles/10.1186/s40064-015-1254-6
