Mountain biking is a popular outdoor activity exercised from urban parks to wilderness and from dedicated bike parks and new summer facilities in ski resorts to user created trails traversing remote forests. Matching increasing use, research on mountain biking is of growing importance for mountain bikers and other user groups in outdoor recreation on one hand, land managers, conservation organizations, the broader recreation and tourism industry and other management units on the other. This inspired the Journal of Outdoor Recreation and Tourism to allocate a Special Issue to present the latest research on mountain biking, including studies from Austria, Australia, New Zealand, Portugal, Slovenia, Scotland, South Africa and the United States.
