I have a question about how teams determine leadership for a single day or stage race. In many sports, there is competition to determine who starts. Coaches often make final decisions, but if rider B outperforms incumbent rider A, they’ll eventually get a shot. Do teams ever have practice sessions where they go head to head to the top of the mountain top finish or time their sprinters? I know they often use results in races leading up to an event, but I’ve never read that a rider was chosen bc he outperformed other riders in training.
