The danger is increased by the presence of inexpert runners and by the change in the pace of the bulls. This stretch turns progressively towards the left until it goes straight down into the final stretch leading into the bull ring. Here the bulls quicken up but the runners in front generally don't have time to do it with the same rapidness. This creates dangerous situations and the statistics reveal a high level of incidents on this stretch of the run.
The image of carrying a rolled up newspaper to guide the bulls along is a traditional one and many believe that it helps the lead the bulls along in this way. And this is so if it is done with experience and under the directions of the pastores or guides taking up the rear. Without coordination from both sides the accelerations could create difficult situations for everyone.
