I'll be there October 31st through November 7th - Wednesday to Wednesday.
Sleep - I like to get to bed between 8:00 -8:30PM so I can get about 6 hours of sleep. Wake up at 2:30 AM, a hour before the buses start running. Have a cup of very strong tea, a toasted bagel with peanut butter to eat. Bring a banana with me to eat while waiting to start. Try not to drink much more liquid than the cup of tea as I've well hydrated the day before (as
@Texas84 says, "check your color"). And use the porta potties at the staging area - those first ones on the course are always busy with long lines.
Eat carbs/protein the day before. But don't go nuts on the carbs, especially anything that can give you some intestinal issues, like beans. Pasta primavera with chicken is a great meal for dinner.
After race, make sure to rehydrate, so grab a bottle or two of either water or Powerade at the finish line. If it's warm and they are handing out cooling towels, grab one also - those things aren't cheap and rD is giving them away. I was shocked to see runners throwing them away after the Princess 10K and Half. Make sure to WALK for a few minutes once you get your medal, grab fluid & a food box and have your picture taken. In spite of rD discouraging you bringing a gear bag (that they give you at the Expo), I bring one for both the 10K and Half. In it is a pack of recovery powder I put in that bottle of water, hand sanitizing wipes and most importantly, flip flops. My running shoes and socks get taken off as soon as possible to give my tired sore feet some rest from my shoes - you will be surprised how much you feet will swell. I eat very little of that food box - most of it ends up in the trash - but I will eat one of the bananas they hand out.
When I get back to my room, my feet go in ice water for about 10 minutes. Then I fill up the tub with lukewarm eater, throw in some Epsom salt and soak my legs for about 20 minutes. Then I shower. You will need some protein with 30 minutes of getting back - my go to is a big glass of chocolate milk while I soak my legs - perfect combination of carbs & protein. And I eat some breakfast. Then nap for an hour before hitting the parks. You need to walk throughout the day.
Then it's repeat for each races.
