It was actually my second MTB race of the season. I also raced the King of Burlingame TT last month. I'll admit that before that race I called my better half while sitting in the parking lot to say something along the lines of "I'm nervous. This isn't fun. Why did I sign up for this? Wah." Don't worry- I got a nice helping of tough love. "Stop being a whiny baby and ride your bike." After being a big baby, I did get on my bike and race. And I enjoyed myself overall. How did I do? I don't know, because my results got lost. I know I didn't win, and I also didn't come in last. Beyond that, I don't know that I care to know how I did.
So if I'm not trying to win, I don't really care about my results and it's not 100% fun 100% of the time- why race at all? Good question.
In conclusion, bike racing is good for learning things and appreciating not bike racing.
