Beginning on Monday with the San Fermin Festival, which is initiated with the firing of the "chupinazo" rocket, followed by the dousing of everyone around you in wine and water, with eight days of the Running of the Bulls beginning later in the week.
The first of eight dashes began Thursday, followed by social networking sites getting bombarded with images of the exhilarating race. Thankfully, here at NESN we have compiled a photo gallery displaying a number of these amazing images.
