This study aims to investigate effects of lessons for long-distance running on students' feelings toward it. This study conducted long-distance running for 20 boys and 20 girls in a class in seventh grade. Results of a pre-questionnaire showed that students who like long-distance running and enjoy it were nine (23%) and nine (23%). Based on these results, this study aims to investigate effects of nine lessons to see students' preferences and enjoyment of long-distance running. Results of this study reveal that the number of students who like long-distance running and enjoy it increases from nine to 15 (38%) and from nine-to 19 (48%). In lessons, students were asked to try to run faster, think about exercise intensity and heart rate, rethink their running forms, and take on challenges to run 2000 meters at their own pace. Through each lesson, students realized changes on their own by becoming aware of differences of their heart rates and their feeling of pain, accomplishing 20-minutes-running, improving their time, and recognizing improvement of their physical capacities. Implications of results are discussed to propose lessons to make student like long-distance running and enjoy it for the future.
