East Harptree Woods TrailO - Sunday 2nd September 2018

British PreO Ranking Event


We are delighted to be organising a TrailO competition in conjunction with the British Middle Distance Championships.  Starts will be timed so that it is easily possible to compete in both competitions and the competition area is very close to the Middle Distance area.

There will be a full length PreO course, planned by team GB athlete Tom Dobra.  We look forward to welcoming both newcomers and veterans, everyone is welcome to come and try out this accessible form of orienteering.

Competition Area: The competition will be staged at East Harptree Woods.  It is located approximately 2 miles from the location of the British Middle Distance Championships which take place on the same day at Stock Hill.  The location is shown here.

Entries: Entries will remain open on SiEntries until Monday 27th August 2018.  There will be limited entry on the day with a £2 surcharge subject to map availability.  You are recommended to email the organiser to reserve a map in the case of late entry.  You can enter the TrailO event via SiEntries here :

Courses: There will be two courses - elite and standard. The standard course will be shorter and less technical than the elite course. The elite course will include two timed controls with two problems. One in the middle of the course after a short timed out, one-way section and one at the end of the course.

Classes: There will be 3 classes – elite open, elite para and standard.

Scoring: One point is scored for each correct answer. There is a penalty of 1 point per 5 minutes (or part thereof) over the course time limit. The timed controls are used as a tie-break. At the timed control, your score is the total time taken to give your answers plus a 60 second penalty per wrong answer. If no answer is given to one or both problems, a penalty of 60 seconds will be given for each unanswered problem.

Map: 1:4000 (ISOM 2017) updated 2018, 5m contours


Timing: Course timing will use SI.  Please bring your own dibber, there will be a limited number to borrow on a first come, first served basis.

Wheelchair users: The surface for the majority of the course is well maintained forest roads and should pose no problems for wheelchair users in either traction or manoeuvrability.

There is a short timed out section which is narrower, downhill and has some extruding roots which additional care should be taken on.


General information: Help and advice for those new to TrailO will be available at registration. Newcomers to TrailO may wish to study the IOF document ‘Technical Introduction to TrailO for experienced foot orienteers’ - here.
