Increase in participation but decrease in performance in age group mountain marathoners in the ‘Jungfrau Marathon’: a Swiss phenomenon? Participation and change of performance over the years has already been explored in detail with large city marathons such as the ‘New York City Marathon’. On the other hand, we do not know how it is a mountain marathon.We have therefore examined the participation and performance of age-class runners on the ‘Virgin Marathon’ from 2000 to 2014.We compared the numbers with a city marathon, the ‘Lausanne Marathon’.
It showed that participation increased in virtually all ages. Surprisingly, the runners were slower over the years in virtually all ages.The difference between the sexes was around 6-7% in the, Virgin Marathon ‘and around 10-12% in, Lausanne Marathon’.
