We've already had colour runs, bubble runs, sweets runs and disco runs, so the next logical step is obviously a fitness happening themed on...the living dead? Following the example set by similar events in the US, Singapore, Germany and other countries, the Japan version of Zombie Run takes place in the seaside surroundings of Chiba's Inage and features a 2km course littered with undead corpses. Sign up with a team of at least four but no more than ten runners, and prepare to fight off ravenous brain-eaters throughout the way. If you're looking for a quirky Halloween experience, this one surely fits the bill. Entry info (in Japanese) is here.
