Jan Ullrich has decided not to participate in the German national championship road race next Sunday in order to concentrate on the Tour de France. "Travelling to and from the race would cost me a day each way," he wrote on his personal website. "Apart from the stress, I would also hardly have time to train on Saturday and Monday. We are convinced that too much running around would hurt my Tour preparations. Therefore, I will stay home in order to prepare myself for the Tour in peace and quiet."
