I am going to be a senior in high school. My first year of Highschool cross (sophomore year) I ran a 17:45 5k. My junior year I ran 15:53. Is it unrealistic to make a goal to run under 15 this year? I don’t want to disappoint myself, but want to keep goals realistic, as obviously since I ran 15:53 my second year of cross, there is still so much room for natural progression in highschool and college. Let me know if this goal of sub 15 is realistic.
