For any triathlon distance (short, Olympic, half-distance and full-distance), competitors spend more time cycling than swimming or running, but running has emerged as the discipline with the greatest influence on overall performance at the Olympic distance. However, there is a lack of evidence on which discipline has the greatest influence on performance in the overall full-distance triathlon (3.8 km swimming/180 km cycling/42.195 km running), especially for the fastest performing athletes of all time. The total race times of 51 fastest triathletes (sub-8-hour) were studied, while for the split times, a sample of 44 participants was considered. The discipline that seemed to better predict total race time was cycling (coefficient = 0.828; < 0.001), followed by running (coefficient = 0.726; < 0.001) and swimming (coefficient = 0.476; < 0.001). Furthermore, cycling was the discipline with the highest performance improvement over the years, whereas running had a slightly decrease. In conclusion, cycling seems to be the discipline with greater influence in final result for the full-distance triathlon.
对于任何铁人三项距离（短距离、奥运会距离、半程距离和全程距离），参赛者在骑行上花费的时间比游泳或跑步更多，但在奥运会距离的比赛中，跑步已成为对总成绩影响最大的项目。然而，对于全程铁人三项（3.8公里游泳/180公里骑行/42.195公里跑步）中哪个项目对成绩影响最大，尤其是对于有史以来成绩最快的运动员，缺乏相关证据。研究了51名最快的铁人三项运动员（总用时低于8小时）的总比赛时间，对于分段用时，则考虑了44名参与者的样本。似乎能更好预测总比赛时间的项目是骑行（系数 = 0.828；< 0.001），其次是跑步（系数 = 0.726；< 0.001）和游泳（系数 = 0.476；< 0.001）。此外，骑行是多年来成绩提升最高的项目，而跑步成绩略有下降。总之，对于全程铁人三项，骑行似乎是对最终成绩影响更大的项目。
