本研究主要以質性研究來探討鐵人三項競賽的成功歷程研究，訪談對象以近五年來，曾參加鐵人三項比賽至少五次以上之選手，且得過分齡組前三名之十位選手為研究對象，研究包括：參賽動機、訓練歷程、練習及比賽歷程中的心理狀態、人格特質、如何將鐵人三項的精神延伸轉移到人生發展上。經過深度訪談後發現：
1、參賽動機方面：關於訓練動機，選手都是因為內在動機（興趣、自我挑戰、健身）而參加，因為動機強，所以持續性也高，選手都想要參加到老、到自己不能動為止。
2、訓練歷程方面：訓練時最重要因素是強度、效率、積極、有計畫的持續不斷的練習，養成規律的生活、注重飲食營養、保持愉快的心情及每天運動的習慣。
3、練習及比賽歷程中的心理狀態方面：選手大都是抱著較積極的想法，以輕鬆的心情去面對比賽，只要努力後坦然接受比賽結果。
4、人格特質及價值觀方面：天性樂觀、做事積極、努力與不服輸的精神、能堅持到底永不放棄。
5、如何將鐵人三項的精神延伸轉移到人生發展上：在人生、事業、家庭的發展上如同鐵人三項一樣，要有著強健的身心、堅忍不拔的毅力，用心的去經營規劃，每天按部就班、循序漸進的使目標逐一完成，使理想循序達成。
The primary objective of this qualitative study is to investigate the Success Process of Triathlon Athletes. The subjects are those who have joined the Triathlon competitions at least for five times in the past five years and achieved at least once of the top three positions in their age group competitions. The research focuses on participation motivations, training process, practice, the mental condition, personality and how to transfer the Triathlon spirit to their life development. The conclusions are as follows:
1. The participation motivation: All players join the competitions because of intrinsic motivations (interest, self-challenge, keep fit). They always persist in this activity because of the strong motivation.
2. The training process: Intensity, efficiency, enthusiasm, and consistent practice with their life routine, attention to nutrition, good mood and regular exercise are all very important factors during their training process.
3. Practice and the mental condition: Athletes are always optimistic toward the competition with relaxed mind and accept the result unperturbed.
4. Personalities: All athletes have hopeful natural instincts, do everything efficiently and never give up.
5. How to transfer the Triathlon spirit to life development: Their life, business and families’ development are just like the triathlon spirit --- They should have strong bodies and minds. The most important thing is that they should manage it with all their efforts and they will be successful.
