General Information

Hot on the heels of the bigger event on 23rd February this event is especially for newcomers and improvers. There will however also be a course especially for experienced orienteers.

Dress: Please check the weather forecast and dress appropriately.  Even though this area is within the city of Edinburgh, it is can still be cold, even on a fine late Winter/early Spring afternoon. Much of the open land faces West and can be windy and cold.

Map: Recently re-surveyed and revised. Printed at 1:5000 scale for White, Yellow and Orange courses, and at 1:7500 for Green courses. All on A4 sheets.

Terrain:  City parkland with a mixture of open fields and wooded hillside, with plenty of rock and contour detail; some steep slopes and crags.  Note that for the small paths, boulders and crags only the most prominent have been mapped. The terrain can be wet/slippery/muddy depending on the weather in the weeks beforehand.

Other Users: This area is very well used by the general public including other runners and many dog walkers.  Please respect their right to be there at the same time as you are orienteering and slow down as necessary.

Dogs: Dogs are allowed and should be kept under close control at all times. 

Course Closure Time: Please note that all competitors should be back at download by 4pm at the latest. Controls will be brought in at 4pm.  

Safety: The area is currently very wet and muddy. Some paths descend quite steeply and have rocky sections, and can be very slippery when wet – take care!  Steep slopes in the forest can be very slippery with leaves over mud, whether you are climbing or descending. There are some high crags that are potentially dangerous.

Coronavirus:  No specific instructions from British Orienteering or Scottish Orienteering yet for small orienteering events, but please heed Government advice in terms of the precautions everyone can take to limit the spread of this virus.

MEDICAL CONDITIONS: You have the option of downloading and completing this Medical Form. It could be life saving if the organisers are aware of any existing medical conditions in the event of an incident. You can leave it at registration/enquires in a sealed envelope that will only be opened if required and destroyed after the event.

Head for Clermiston Road North in the city of Edinburgh.  There is a small public car park on the east side of Clermiston Road North. There will be a kite at the entrance to the car park.  Competitors should turn in at the kite and follow signs thereafter to the off road competitor only parking which within Barnton Quarry, (post code EH4 7BN). Please park as directed as space is limited.  Barnton Quarry is a disused stone quarry, later used as a military command centre. It is now being converted into a cold war museum and education centre. The surrounding quarry walls are steep and high and there is equipment stored around the parking space. Please ensure that none of your group climbs on the walls or interferes with any equipment.

It is possible to come to this event by public transport. Check Lothian Buses for information. The nearest are the stops “Clermiston Road North” (services 21 and 200), about 100m from Registration, and “Clermiston Crescent” (services 1 and 26) at 250m.  Other buses, mostly those heading towards the Forth Bridge, also pass along Queensferry Road reasonably close to this event.

Registration & Start Times

You should still leave enough time to arrive, park, register and pay and get to the start by 3pm.  

COURSE CLOSURE TIME: Please note that courses have a closure time of 4pm after which controls will be brought in.  You should be back at Registration/Download by 4pm.  Whether you are a newcomer or have been to a lot of events, please try to come and start early if you think you might take a long time over your course.

Course Information

As usual for ESOC local events there will be White (1.2k) , Yellow (1.9k) and Orange (2.4k) courses.

There will also be a Green (3.8k) course with an extra option for ‘corridor’ training especially for experienced orienteers. For this corridor training you have only a narrow strip of the map, typically 50-100m wide, centred on the route between controls. So you have to navigate carefully to stay within the strip (or you’ll be off the map!). It’s a good exercise on an area with lots of paths, like Corstorphine Hill, because it’s very difficult to take an easier route going round the paths – the mapped strip will usually be away from the relevant paths.

NOTE: The courses have been planned to be very different to those offered at the bigger event held on Corstorphine Hill on 23rd February.

Explanation of colour courses

  • White are very easy with all controls on paths. They are mainly used by 6-10 year olds and family groups.
  • Yellow use simple linear features like paths, walls and streams. They are mainly used by under 12’s and family groups.
  • Orange progress to basic use of the compass and route choice. They are ideal for novice adults or experienced youngsters.
  • Light Green are ideal for improvers as the navigational difficulty begins to increase and uses simple contours and point features.
  • Green are used mostly by experienced under 18’s and adults wanting a short but challenging course with a very hard navigational difficulty.
  • Blue are a longer, more physically demanding course in comparison to the green. The distances are more varied between controls and the course attracts experienced orienteers.
  • Brown & Black are very physically demanding and have a very hard navigational difficulty. They are for experienced orienteers only.
  • Score means visiting as many controls as possible in any order in a specific time, like 45mins.
