No, no, no, I think you need to make sure you are well rested and that your bike is in good riding order. I would just lie around and save your energy, I am sure your skills are fine. I would also recommend my training diet of lots of cold beer, nachos with extra cheese and chili, and big gordo burritos. After all, the winners get to go to South America and you have to train for the food too. Double helpings too. Its impolite to refuse the hospitality and everyone eats two portions each meal.
