I specialize in middle distance (400m/800m). In high school I was our team captain, and we won the 5A state championship 3 years in a row. Individually I was 5th in state for the 800m and set a couple school and state records on various relay teams. I ran in college for Penn for a couple of years, but ultimately quite because I just wasn't it at the time. After college, I returned to my old high school and coached the middle distance for 7 years. During that time, I absorbed everything in sight regarding various training philosophies and tactics and coached multiple athletes to and relay teams to state championships of their own.
Today I continue to run half marathons, since the shorter stuff is just too hard on the body once you get over 30 haha. My best half so far is 1:17:58, so about 5:58 per mile.
