The triathlon Mixed-Team-Relay (MTR) is a new race format present for the first time at the Tokyo Olympic Games in 2021. The results of the ITU Triathlon Mixed Relay World Championship from 2014 to 2019 were collected to provide practical suggestions for forming a successful MTR, such as the importance of each leg and discipline on MTR and Super-Sprint performance. The total relay time (Trelay), the time of each team member (leg-from 1 to 4) (Tleg), and the time of each single discipline (swim, T1, cycle, T2, run) were collected from the official website. Inferential analysis was performed to assess prediction and differences between variables. Leg 3 was shown to be the most important to predict Trelay (0.41), which is also the slower. For both Trelay and Tleg, cycling resulted as the most important (>0.60) and longer (~52%) portion, followed by running and swimming. However, higher importance in swimming was found in successful teams compared to running. For a successful MTR, we suggest: (a) use short-distance specialized triathletes; (b) strengthen cycling and swimming; (c) position in legs 1 and 2 athletes capable of racing in a group; in legs 3 and 4 athletes capable of racing in a non-drafting situation.
铁人三项混合团体接力赛（MTR）是一种全新的比赛形式，于2021年首次亮相东京奥运会。收集了2014年至2019年国际铁人三项联盟混合接力世界锦标赛的成绩，以提供关于组建一支成功的MTR的实用建议，比如各赛段和项目对MTR及超级短距离赛成绩的重要性。从官方网站收集了总接力时间（Trelay）、每个队员（第1至4赛段）的时间（Tleg）以及每个单项（游泳、T1、自行车、T2、跑步）的时间。进行了推断性分析以评估变量之间的预测和差异。结果显示，第3赛段对预测Trelay最为重要（0.41），且该赛段速度也较慢。对于Trelay和Tleg而言，自行车赛段最为重要（>0.60）且占比最长（约52%），其次是跑步和游泳。然而，与跑步相比，成功参赛队伍在游泳项目上的重要性更高。对于一支成功的MTR队伍，我们建议：（a）选用短距离专项铁人三项运动员；（b）加强自行车和游泳训练；（c）在第1和第2赛段安排能够团队比赛的运动员；在第3和第4赛段安排能够在非跟骑情况下比赛的运动员。
