I started to run 14 or 15 years ago, when I quit smoking. Little by little I started to like it. The big change came when I got a watch that measures the distance and the speed. My first race was a half- marathon. I beat my best time for a half-marathon, which was an hour and 40 minutes. It was a very hot day and maybe I didn't drink enough. I felt dizzy and my legs were weak. I finished the marathon, but not with the time that I wanted. https://339efcb25eb75e967b0d-ff8eeadd950d51fd1fc939dca75b3973.ssl.cf1.rackcdn.com/assets_default.swf
