The first running of the bulls of Sanfermin 2007, with bulls from the Dolores Aguirre Seville bull-ranch, was one of the most crowded ever in these last few years. Thanks to the multitude of people the run started five minutes later than its proper time. The pack quickly broke up and the bulls ran separately and there were a lot of slip-ups due to the poor state of the pavement. One person received a goring in first stretch of the run in Santo Domingo. Three more were also take off for hospital treatment with slight wounds. The bulls took 2 min: 40 sec. to cover the distance.
The pack came out of the pens in Santo Domingo behind the bell-oxen and some of the bulls began to slip up within the first strides and they charged some runners on the right side of the fencing. One runner got caught between two bulls and he was gored by the rear bull coming up behind. It was seems to have been the only goring of the day. Apparently, the runner is an Australian man. The bell-oxen kept the bulls in behind them and while the bulls threatened to make charges right and left they did not stray from the bell-oxen.
At City Hall square the pack began to loosen but the bell-oxen continued to run in front. The pack charged past at a fast pace across the square in along Mercaderes street. It was difficult to make out the bulls at times due to the packed number of runners. The rear bull shaped up to charge on both sides but without causing any real risk to the runners.
The pack came across Mercaderes without slipping up but when they reach the fencing on the left corner they fell and here they began to split up and separate. There were now two front running bulls and four others coming up behind and this position was kept up for the rest of the run. Estafeta Street was packed with runners and here the most spectacular part of the run could be seen. However, it was not easy for the runners to get close in front of the horns.
The two leading bulls charged past the Telefónica stretch with two bell-oxen following behind them. Then the other four bulls came up in single file and they entered one by one into the final stretch which leads into the bull ring. The minders quickly lead the bulls towards the pens with their capes. A massive number of runners came charging into the bull ring behind the last of the bulls but there was no danger as the bulls were lead away to the safety of the pens.
