Pacing and Performance Analysis of the World’s Fastest Female Ultra-Triathlete in 5x and 10x Ironman The aim of the present case study was to analyze the performance of the world’s best ultra-triathletin, which set up a new world record in Quintuple Iron (5xironman) and Deca Iron (10xironman). At the time of her world record in Quintuple Iron, she was 35 years old and at the time of the world record in the Deca Iron 36 years old. The distribution of time spent in the individual disciplines and transition zones was 8.48% for swimming, 51.67% in cycling, 37.91% during running and 1.94% in the change zones. There was no difference between the individual race days of average speed, neither when cycling nor running. The running pace varied within a day larger than the bicycle pace and also varied between the race days stronger.
In summary, it can be said that the world’s best ultra-triathletin tracked a constant (even) strategy for cycling and running without significant deviations within or between the race days for the world record in a Quintuple and a Deca Iron Ultra Triathlon.
