在鐵人三項運動參與者中，有一群不以競爭名次為目標，而是以完成型選手身份自居的休閒型鐵人。這群人抱著「完賽即是勝利」的自我挑戰態度，從參與休閒活動角度出發，認真投入這項戶外休閒運動。對於這些鐵人三項賽事參與人數佔大宗者，在依序挑戰游泳、自行車與跑步的運動情境裡，共同經歷一段報名、練習與完賽的歷程。為了瞭解戶外休閒運動領域中，這一個將鐵人三項作為認真休閒活動而持續投入參與的現象，本文透過國內外文獻回顧，以休閒型鐵人為對象，依照「報名參與動機」、「賽前認真準備」、「當下堅持邁進」與「完賽就是勝利」四個階段歷程，針對歷程中的體驗感受進行歸納整理，並據以提供未來此一戶外休閒運動現象議題的研究方向與建議。

Among triathlon participants, there was a group of recreational triathletes who declared themselves as completion-oriented athletes. This group of people deeply involved in this recreational sport with the belief of “whoever finishes will be a winner” and kept their attitude toward self-challenge. These triathlon participants accounting for most enrolling percentages of competition events shared the same process of registration, practice and competition-finishing following series of challenges from swimming, biking and running in the sports content. In order to interpret the phenomena of taking triathlon as serious recreational sport for continuing involvement, this study reviewed the related literature for recreational triathlon participants’ experiences of competition-finishing process based on four stages, including: “decide to register”, “prepare seriously before competition”, “keep moving forward” and “victory in the finishing line”. Also, some directions and suggestions were provided for future researches to make this study more contributive.
