The Age-Related Performance Decline in Ironman 70.3 Although age-related acceptance of performance was well investigated in sport, little is known about such a decrease in triathlets for half Ironman distance.In fact, the few existing studies focused on specific aspects such as top events, elite groups, some consecutive years, individual locations or age categories rather than analyzing all available data. The aim of this study was therefore to examine the performance of triathlets in the three disciplines (swimming, cycling and running) as well as for the entire conclusion by analyzing data from Half Ironman Finishers (690 races, years 2004 to 2018, 206 ‘524 women (24.6%) and 633'576 men (75.4%), a total of 840'100 athletes). The age-related acceptance of the achievement at Half Ironman began at the earliest when swimming (from the first age group) with a smallest delta between 35 and 49 years in men and 40 to 54 years in women.
The performance drop started in men and women at 26 and 28 years to run;At 34 years for men and 35 years for women while cycling;And at 32 years for men and 31 years for women regarding the conclusion.The results can be used by trainers and recreational awards alike to plan a career.
