I am heading to Iowa for a week long trek by bike across the corn state. Going with a clan of beer/booze hounds who are officially a drinking group with a biking problem. A few adult beverages will be consumed and they are asking questions about caloric burn. They want to make sure the spandex can hold 'em.

For the sake of our discussion, one serving of alcohol will be as follows:
• Beer – 12 ounces
• Wine - 5 ounces
• Booze - 1.5 ounces

Each of these has roughly 14 grams of alcohol which burns at a rate of 7 calories per gram netting 100 calories of alcohol (not carbs) per serving. The booze has “0” carbs but the beer averages 5-8 carbs and the wine 4 grams of carb per serving so this is in addition to the alcohol.
