Do yourself a favour and skip the 'pasta party', the night before- no benefit to this whatsoever. If its just a training ride: eat as normal. If its a really tough ride, or a race: rather slightly increase your good carb intake ie. bananas, melon, potato, sweet potato and some dried fruit. Make sure your evening meal contains healthy fats and good protein. Remember, your glycogen stores can only be so full. If you've done nothing excessive the day before, then your glycogen stores will only be slightly depleted, a huge bowl of 'empty' carbs (pasta) isn't going to do anything for you other then probably make you put on weight as you'll probably be in a caloric excess for the day. Muesli/oats in the morning, isn't the best option either, as it takes too long to digest. What hasn't digested by the time you start your ride, will just sit there in your gut and soak up fluids, likely leaving you feeling a little bloated.
