Wow where do I start?
My most athletic period of my life was when I was 11-13. I did everything, played on teams for Basketball, Soccer, Track, Swimming, Skiing, At that age, I was an incredibly good endurance runner for my age. Got 2nd in the 800m, 1500m a couple of times, participated in one winning 100x4 relay. Won a cross-country event.
Shitty thing is I gave that all up when I was 14 and let myself get fat for a while.
