Performance and Pacing of Age Groups in Half-Marathon and Marathon The aim of the present study was to investigate the age-related differences in performance and pacing in a half marathon compared to a marathon. All Finishers (N = 9137) of the Half Marathon (N = 7258) and the Marathon (N = 1853) Ljubljana 2017 with available data for intermediate times during the race were analyzed on the pacing. Half marathon runners were slower at women than marathon runners (2.77 ± 0.35 compared to 2.86 ± 0.39 m / s), but faster in men (3.14 ± 0.45 compared to 3.08 ± 0.46 m /s). In both races, the age group was <25 years the fastest and age group> 54 years slowest. All age groups showed a positive pacing (decrease in speed in the race) in both the renown distances and the sexes, each segment being slower than the previous one. In the marathon, however, a final spurt was observed, but not in the half marathon. For most age groups, the pacing in the half marathon was more even than in the marathon.
In summary, it can be said that the age group finishers of the half marathon reduced the running speed during the race, showed a more uniform pace than the marathon runners and no final spurt showed. The whole work can be found under https://www.mdpi.com/1660-4601/16/10/1777
