Longitudinal Performance Analysis in Ultra-Triathlon of the World’s 2 Best Master Triathlete This case study includes the analysis of the services of two ultra-triathlets, which have participated in the last three decades of ultra-triathlon competitions (Double Iron and Triple Iron Ultra Triathlon). Longitudinal cut data for performance development at Ultra-Triathlon athletes over many years are rare.The prediction of age-related performance in the various disciplines for triathlon events (swimming, cycling and running) is required so that the organizers can set realistic goals (timelins) for master athletes at these events. Athletes A and B had 34 and 53 holdings at Double Iron Ultra Triathlon at the age of 35 to 55 and 40 to 69 years and 26 and 20 participations in Triple Iron Ultra Triathlons aged 33 to 51 and 40 to61 years. Nonlinear regression analyzes were performed with the three disciplines and total output against age. The average performance drop in triple Iron ultra-triathlon was 0.62% per year for swimming, 0.19% per year for cycling and 0.98% per year for running for athlete A. For athlete B, a positive change in swimming (0.19% per year) and cycling (1.12% per year), but a negative change in running (1.34% per year) detected. Running is the discipline with the largest performance drop rate for both athletes, both in the double as in the Triple Iron Ultra Triathlon.
The Timeout for Double Iron Ultra-Triathlon seems to be too short, which makes it difficult for Master athletes older than 55 years, it is difficult to end the race as part of the event regulations.
