11 March 2024: Latest Update - The March 2024 British TrailO Newsletter is now available.  See News to read more.

Trail Orienteering is one of four disciplines in orienteering - the others are Foot, Mountain Bike and Ski Orienteering. TrailO provides an orienteering competition for people of all levels of physical ability, including those who are physically challenged and may be confined to wheelchairs.  For more details about how Trail Orienteering enables those with reduced mobility to compete, see the section on The 'P Class'.

TrailO has two formats - TempO, the 'speed' form of TrailO where all competition activity is timed, and PreO, the 'classic' format with generous time limits but with one or more timed controls. More information on the PreO and TempO event formats can be found on separate pages: Event Formats: PreO and Event Formats:TempO. At European and World Championship events there are also relay competitions. Virtual TempO is also now a very popular form of competition.

TrailO Development Steering Group

The overall management of TrailO in the UK is the task of the TrailO Development Steering Group, one of several Steering Groups that support British Orienteering in the provision and development of the sport.

The TrailO Development SG is currently chaired by Graham Urquhart.  Full details of the SG's Terms of Reference and membership and the minutes of previous meetings (once approved) are available on the main British Orienteering web page - see: Steering Groups (the SG's are listed alphabetically - look near the end of the page!).
