Competitive?

My one, entire goal for Diamond Girl was to finish, to actually cross the finish line and not be last. That was really my only goal and the whole reason I trained - I wanted to be able to say, "I AM A TRIATHLETE". However, now it's 3 days later and I've been thinking a lot about the race as a whole. All I can think is, "I could have done better. I could have beaten (fill in name here)." All of a sudden I'm competitive and annoyed at myself for just finishing and not kicking ass. Although hindsight is 20/20 and I'm not sure at the time I could have gone one second faster but I do know that next time, I'd like to try. I want to work hard on my run - they say, "all triathlons are won or lost in the run". I was pretty bummed when I heard that initially bc I knew I'd never be a fast runner but now I'm willing to give it a really good try. I know it can get better with some old-fashioned hard work and dedication. Of course, the bike and swim can always use enormous amount of improvement but the run is a disaster (and by run, I mean walk!). To quote my lovely teammate Tara, "you don't have to go fast, you just have to go - well, that was true before I was a triathlete. Now I want to go fast."!! Now I'm ready to get a move on, do my running drills, actually listen to what Andy says and even more - do the solo run workouts. Push hard, run fast, eye on the prize...
