Morning group rides: I get up half an hour before it would be necessary for me to leave. Quick shower, down two or three bowls of cereal down the hatch, slam a bottle of water, drop a fatty in the water closet, and out the door.
Races: Get up several hours before the race. I like to have my final meal about 2hrs before the start, and usually down a gel or powerbar when people are gathering at the line. One bottle of sports drink, one bottle of water. Alternate between the sports drink and water, preferably using the sports drink up first. A good spray of water down the back feels good towards the end of a race.
