In the 161 km marathon, the age between 40 and 44 were the years with the highest number of successful finishers.


For 100 km, runners between 45 and 49 were the most successful athletes. When analyzing the performance of 2,067 100 km runners around the world during the past 59 years, an increase in the number of participants over 60 years was identified. Generally, ultramarathoners were the oldest, compared to marathon and half-marathon runners. In summary, these studies have shown that the runners are male, aged over 35 years, and have undergone systematic training. Previous research has been carried out in order to understand the profile of runners (i.e., sex, age, and economic status), age peak, and performance progression (PP), especially in 50 km and 100 km runs. In recent years, there have been a consolidation and increase in the number of Ultramarathon (UMs) events around the world.
