My coaches and I wondering why I could not break 2:10 in the 800m as a freshman. My freshman year was my first time running more than 400 meters. I ran a time of 1:33.23 in the 600m during the indoor season, 54.78 in the 400m dash, 24.60 in the 200m dash, and 21:38 5k . Is my problem not having sufficient endurance, mental or is it strategy ?
