Thousands of participants have signed up for a thrilling game, a zombie-infested race in the Philippines, which involves challenging tortuous tracks ahead, and dodging the "walking dead." 　　Around five thousand runners ran for their lives while being chased by hordes of "zombies" in a survival-themed race in the Philippines over the weekend. 　　Taken from a popular zombie race in the United States, thousands of runners raced to finish the five kilometer course. Meanwhile, they had to tackle a series of natural and man-made obstacles, such as zombie attacks. 　　Two hundred actors dressed as post apocalyptic zombies hid behind trees, bushes and rocky uphill climbed to surprise the runners and symbolically eat their brains out by stealing health flags attached to the runners' waists. 　　Runners are considered "dead" when all of their three flags are stolen, but they can get additional flags by accomplishing certain optional obstacles that often guarded by the zombies. 　　To keep both runners and zombies safe from injuries, organizers imposed a no-contact rule that forbids the zombies from any physical contact with the runners aside from taking their flags. 　　The event organizers plan to host similar races across Manila in the upcoming months after the success of the first zombie race.
