What a rough week.
I hope your Mom is going to be OK. How scary. That, and then a forest fire? WOW! Great job on getting any kind of workout in.
You are ready for your race. Have faith in your training.
I know for me, my first 2 years of tri's... I would do nothing but think about my upcoming race for a good week ahead of time. Then the night before I would focus on it, and think about it. This resulted in no sleep. Then the day of the race, I had to sit down and think about the race and visualize what I was going to do.
This year... I have tossed all that out the window. I tell myself that I trained for my race, and thinking about it doesn't make me perform any better. In fact, it just stresses me out and keeps me from sleeping.
Before my 2 races this year, I slept like a baby the whole night through. It was heavenly. The day of the race I got there and just did it. And the races were fun!
Moral of the really long story: You are trained and ready for this. Know that. Good luck.
