It sounds like you got all the key components in. You're totally ready.

It sucks that you had such a rough week. I'm glad your Mom is doing OK. Realize that your ability to hold it together and get the necessities done this week proves how mentally tough you are. That should make you feel better going ito the race.

Spend the next couple of days visualizing. Think about the start, the transitions, the technical parts of the bike and the strong finish. Imagine them happening from the perspective of being in your own body, not on the outside watching yourself and visualiz success.

Good luck.
