Why not treat yourself to a hair-raising hike around some of the City’s scary streets and historic haunts?
Choose your distance, with 25km and 10km options, gather your bravest guys and ghouls to make up a team – or go it alone if you dare and meet up with other chilling challengers. Dress to distress, and the creepy dungeon keepers at The Oval start and finish will meet, greet & shock..
