KSH,
it's been a long journey, but like Frank- you did it your way.
Enjoy your day of racing. Someone told me before my IM in 2006 to enjoy the day like a celebration or party. You've worked very hard for 8 months and now's the time to enjoy and smile and savor every moment on the course. Even the tough moments- enjoy them as well. It helped me keep my perspective on race day and really enjoy my moment in time.

Here is what a good friend e-mailed me the week before my race:

Just a few short days until Redman (or in your case, Louisville). I want to wish you good luck and give a few final thoughts to keep with you on race day.
Trust your training. You have prepared for this event. Know that you have it within you to do this. You will doubt yourself, but trust the preparation you have done.
Race the race you have trained for. Do your race at your pace, don't get caught up in what those around you are doing.
Enjoy yourself. This will be a monumental accomplishment.
I'll be looking for you at the finish line.
Good Luck

While I won't be physically there looking for you at the finish line, I'll be looking for you online.

HAVE FUN!!!! GOOD LUCK!!!!!
