<P> The length of the run is 875 meters ( 957 yards ) . It goes through four streets of the old part of the city ( Santo Domingo , Ayuntamiento , Mercaderes and Estafeta ) via the Town Hall Square and the short section `` Telefónica '' ( named for the location of the old telephone office at end of Calle Estafeta ) just before entering into the bullring through its callejón ( tunnel ) . The fastest part of the route is up Santo Domingo and across the Town Hall Square , but the bulls often became separated at the entrance to Estafeta Street as they slowed down . One or more would slip going into the turn at Estafeta ( `` la curva '' ) , resulting in the installation of anti-slip surfacing , and now most of the bulls negotiate the turn onto Estafeta and are often ahead of the steers . This has resulted in a quicker run . Runners are not permitted in the first 50 meters of the encierro , which is an uphill grade where the bulls are much faster . </P>
