Effects of The Performance Level and Race Distance on Pacing in Ultra-Triathlons The aim of this study was to investigate the impact of the performance level and race distance to the pace at Ultra Triathlon (Double, Triple, Quintuple and Deca Iron Ultra Triathlon), which is defined as the relative time (%).which is spent in each discipline (swimming, cycling and running). All Finishers (n = 3'622) of Double, Triple, Quintuple and Deca Iron Ultra-Triathlon between 1985 and 2016 were analyzed and divided into quartiles (Q1, Q2, Q3 and Q4), where Q1 is the fastest and Q4 slowest. The performance of all non-finishers (n = 1'000) in the same period was also investigated. Double and Quintuple Iron Ultra Triathlons (24.4%) revealed the highest rate of non-finishers, and Deca Iron Ultra Triathlons achieved the lowest rate (18.0%). DECA IRON ULTRA triathlets (6.7 ± 1.5% and 48.8 ± 4.9%) proved to be the fastest and double (9.2 ± 1.6% and 49.6 ± 3.6%) Triple Iron Ultra triathlets than the slowest, with Q4 the fastest group (8.3 ± 1.6% and 48.8 ± 4.3%) and Q1 the slowest (95 ± 1.5% and 50.9 ± 3.0%). When running, Double Iron Ultra Triathlets were relatively fastest (41.2 ± 4.0%) and Deca Iron Ultra Triathlets (44.5 ± 5.4%) slowest, with Q1 the fastest (39.6 ± 3, 3%) and Q4 The slowest group was (42.9 ± 4.7%).
Based on these findings, the conclusion was concluded that the fastest ultra-triathlets spent relatively more time with swimming and cycling and less time with run, underlines the importance of the role of the latter discipline for the entire ultra-triathlon performance. In addition, coaches and ultra-triathlets should consider the differences in the speed between Double, Triple, Quintuple and Deca Irron Ultra-Triathlons.
