Other than the TT, Levi needs to try to take 3-5 seconds off Cadel by making a break at 2-3km to go in all the remaining stages. If cadel cannot follow and there is a clean break where the officials give him and the people with him a different time than the peleton, he can gain some time. This may only work once though and the fact Levi isn't known for his explosive breaks, he may not be able to do it. If he could get a team mate to explode for him and then he can just power ahead, that might work.
