Ah... that is so true RnR girl.
I think it's so easy for us to lose focus on our own personal accomplishments... when we are surrounded by people who do so much more.
We forget, that what we do on a weekly basis is more than most Americans do on a yearly basis. Of course, it's easy to lose sight of that, when the only people you socialize with are amazing athletes.
It also sucks how a bad race can erase everything good we did to get there. Hey, I have bad training days, and I am sure as heck going to have bad racing days.
Personally, my attitude this year is that I'm going to out there and just have fun. I have trained, I put in the time... my body knows what to do.
Stressing out or getting "serious" on race day doesn't change anything. Well, actually, it just makes me stressed out and miserable.
Before the duathlon, I just "let it go". And you know what, I got sleep the night before... AND I did exactly as I would have done if I had stressed about it. During the race, I just told myself, "Hey, you do this in training all the time. Just run and do what you can do."
Anyhoo... I'm not sure if I was "on topic" with my reply... but your post did make me think those thoughts. 
Yesterday I climbed a hill, a very long, technical hill on my mt bike. At the top, there were two dudes. They looked up and said "did you make it?". I gasped Yep, did you? Nope....they did not.
That's great! Congratulations!
A couple of weeks ago, at a bike rally... I took a little bit of pride when my boyfriend had to stop and rest going up a steep hill and I just pedaled on by. I might be slower, but I can take a hill.
