Posted before I finished my jumbled thoughts......
RACE RETREAT - worth every stinkin' last penny. pre-race food, private bag check, private porta potties and post race food!!! It was heavenly being able to go into that tent and wind down after the race.
Post Race Meals - I had a beer, steak & fries at BOG dinner last year. It was perfect.
Pre-race Meals - I'm not a carb loader. I eat the same way I do at home so I know I won't end up with bloating, upset stomach, etc. I usually have a banana & an organic cereal bar in the morning before my runs.
Fuel during runs - I've tried a few different gel shots and the texture makes me gag. I usually bring swedish fish & pretzels and wash it down with a mix of 1/2 H2O 1/2 powerade and it works great, but I'd like something that doesn't take up as much room in my pockets. I plan to pick up some sport beans and try those out next week.
Speaking as a Floridian living near WDW for the past 20+ years, it's a total crapshoot: it can be 80 or 20, all depending on whether we have a cold front come through. Layers are your friend! I always plan an outermost layer that I can wear on its own if warm, or over other other layers if cold, as my outfit in winter. And if it's somewhere in the middle, I always have throwaway layers I can wear while waiting to start and toss once I'm moving and warmed up.
We have dinner at Via Napoli that night.
