Dave Mitchell started mountain biking in 1986 with a group of friends who became the core of the Canterbury Mountain Bike Club. The search for epic adventures started early and continues to this day and has included a 26-day off-road traverse of the South Island riding tracks and trails as close to the main divide as possible, as well as multi-day trips in many other countries of the world. He regularly contributes articles to a range of different magazines and also produces an annual mountain bike calendar of his photography. He lives in Christchurch with his partner Ditte and their dog Tinker. Geographx is a Wellington-based cartographic design and mapping company with a reputation for visualising New Zealand's wild and varied terrain in new and meaningful ways. The company was started by Roger Smith, formerly a geologist, pilot, farmer, amateur botanist and occasional participant in a variety of outdoor wilderness activities.
