Former Fat Guy to Triathlete

I completed my first triathlon yesterday. It was a beginner race in every sense of the word. It was much shorter than even sprint distance. We swam 200 yards, biked 6 miles and ran 2 miles. My goal was to complete it under an hour and I did much better than that. I completed it in 51 minutes and 12 seconds. I was actually the first person to finish. A little background about me. Less than 1 year ago I weighed 410 lbs. I wasn't a fat kid. In fact I'm a former college soccer player. I was also an above average high school swimmer. Last Memorial Day weekend I decided I was done being fat. I started eating right and working out. I've lost a total of 175 lbs and now weigh in at 235 lbs. I'm 6'2" so I carry it pretty well but I wouldn't mind losing another 30 lbs or so. In the race I completed yesterday my swim was the best event. My PR in the 200 is 2:08 but that was back in high school. I hadn't really swam at all since then. Yesterday I swam it in about 2:30. Not great but I thought it was all right for my first race in more than 20 years. Consider my bike isn't a racing bike I thought I did okay on that leg. I have a Jamis hybrid and I averaged 3:46 a mile on a very flat course. I run the 2 miles in under 20 minutes which I was very happy about that because I was pretty tired by that point. I think this is going to be my new sport.
