With the aim of achieving the race goal it will be mandatory to train different physiological, biomechanical and psychological factors.

The Marathon (42195 m) is one of the most participative endurance competitions. Women presented numerous differences based on their performance which suggested different pacing behaviours. In men there were little significant differences based on athletes’ performance which implied a similar pacing behaviour. In men, no statistically significant changes were found between performance group and splits. With the aim of comparing the pacing between sex and performance the average speed was normalized. 4 different groups were created based on sex and performance. A total of 2295 runners, which took part in Berlin’s marathon (2017), met the inclusion criteria. The purposes of this study were 1) to analyse the different pacing behaviours based on athlete's performance and 2) to determine whether significant differences in each race split and the runner's performance implied different race profiles.
