I'm guessing the race is today? (Sunday)
It's very close.
Today (Monday) = nervous day
You've done the work, you've got the fitness, so you've already taken care of the biggest factors. Now just stay in the mindset you want (loose, relaxed, focused,... Whatever works best for you) and know that you have done the work and are riding STRONG! :)))
Have a great race and enjoy it, you're THERE at this big event, how cool is that!?
