When to carb up?

[ny biker]

I was told to carb up starting 2 days before. But you still want to try eating high fiber carbs, ie oatmeal, whole grain bread, Dream Fields pasta which has lots of fiber

Also, no fatty foods. No spicy foods. No sour foods (ie. pickled items/hot and sour soup)

Drink tons of water until your urine is a light yellow starting 1-2 days before.

I would not eat high fiber carbs before a big ride unless my diet normally includes high fiber carbs. Otherwise the results could be extremely unpleasant.

Same with drinking water -- I don't drink more before a big ride because I drink plenty of fluids every day.

You should be doing training rides leading up to an important event, and the food and beverages you have before the event should be similar to what you have learned is best for you based on what you eat and drink before the training rides.
