"Why do you do this? Live a little, you are nuts". This is what I hear over and over. To get to where I am now has not been easy. It has been waking up at 4 A.M and heading to races, sacrificing a Friday night in order to rest or spending my Sunday morning in a lake. It is not quite the typical obsession to have for a senior in high school, yet it is what I am and what I love. The world of triathlons has become such a big part of me this year. I have completed three triathlons, winning my age group in my first one and one half marathon in preparation for my first half iron-man triathlon. To me, this is my way to build strength both physically and mentally. The dedication and training are what I am and what I love.
