Twalk is a twenty-four hour orienteering event in Christchurch, split in to five legs, each around 15 to 20 kilometres long.
Each leg has around 10 to 20 controls, which will be hidden on features marked on the map and described by a cryptic clue.
The first leg is compulsory, as it leads from where you are dropped off to the Hash House. From there, competitors may choose to participate in as many or few legs as they choose, leaving when they like (there is a compulsory 30 minute break between legs). Legs two to five form loops which end up back at the Hash House, and can be cut short if required.
