I ran cross country in high school, but I started running again less for the fitness benefits and more for the thrill of conquering human limitations. For that reason, a few years ago I decided to try my hand at triathlons. I really liked them, but found the running portions were where I thrived physically and mentally. I started focusing on running more. I started running marathons because I wanted the challenge. I enjoy pushing myself and take pride in conquering what I thought I was difficult. A marathon is an ideal goal for not just motivation, but a deluxe edition of motivation. It’s not easy to prepare yourself for a race like the San Francisco Marathon. And for that reason I found myself training six days a week. Easy goals are easy to neglect. Difficult ones require your full attention, and once that goal has it, it won’t let go.
