Children run during the “encierro txiki” (small bull run) of the San Fermin Festival in Pamplona, northern Spain, on July 13, 2016.

On each day of the festival six bulls are released at 8:00 a.m. (0600 GMT) to run from their corral through the narrow, cobbled streets of the old town over an 850-meter (yard) course. Ahead of them are the runners, who try to stay close to the bulls without falling over or being gored. / AFP / ANDER GILLENEA (Photo credit should read ANDER GILLENEA/AFP/Getty Images)
