Abstract. Introduction. The problem of improving the preparedness of highly qualified athletes requires solving questions about the individualization of the training process based on taking into account the sports form of the athlete, the specific conditions of the competitive distance, as well as substantiating the intensity and volume of various types of training and their importance depending on the period of training. The purpose of the study is to develop an individual running training program for triathlon and experimentally check its effectiveness. Methodology. The experiment was conducted as part of the preparations for the Ukrainian triathlon championship. A student of the Cherkasy National University named after Bohd Khmelnytsky, who is a master of sports of Ukraine, took part in the study. The formative part of the experiment involved the development of an individual running training program, its implementation in the training process and analysis of its effectiveness. The following research methods were used in the study: analysis of scientific and methodical literature, pedagogical testing, pedagogical experiment. The main characteristics of special running fitness were measured using GPS speedometer. Results. The effectiveness of the individual running training program for the Ukrainian Winter Aquathlon Championship was developed and experimentally verified, which was based on information about the current state of the athlete's sports form, the priorities of different types of training were determined depending on the training period and the justification of individual intensity, pace, volume and combination of different types of training. The content, forms, methods and means of preparation for the final competitions of the season have been improved. Provisions on the methodology of managing the training process and competitive activity in triathlon have gained further development. Conclusion. The effectiveness of the presented individual running training program has been experimentally proven.
