General Information

Planner's Comments

Thanks so much to everyone who attended this event. I've received lots of great feedback on both the planning and mapping. When Janet offered me the opportunity to plan this race, I initially thought I only needed to make a minor update to the map. However, the reality was that the map required a major update. As a beginner mapper, I faced the challenge of creating an accurate version with all the necessary changes. Thanks to those who pointed out the aspects that needed modification.

Regarding the planning, I never enjoyed running in that corridor leading to the southernmost part of the map, so I had to find an alternative route using the small neighbourhood area near the woods. I reviewed previous events and made an effort to avoid using the typical controls already employed in those races.

A big thank you to Catherine, Jayne, and Janet for all the support. Special thanks to James Murdoch and Alison for trying the courses and sharing their feedback. Lastly, I appreciate Paul and Peter for generously sharing their planning knowledge, making my courses get better.

What Went Well

Vicente’s courses, pretty much from the get go, and as far as I’m concerned, that’s the most important thing;
The many, many improvements that Vicente made to the map.

Organiser's Comments

It was a great pleasure to organise an event that ended with a party, in the form of the ESOC social and prize-giving. All credit to those members of the event team who spent the entire day on the hill and were still standing as the last numbers from the well-known Orienteering Bangers playlist hit the decks. 

My talented team of volunteers had promised to deliver championship racing and quality SoSOL orienteering in the heart of the city, and this they did in spades. It was a beautiful autumn day, which gave all the runners the best possible chance to enjoy Vicente's fresh take on a favourite area. They all agreed that it was muddy, but they all said they had known it would be. A huge number and range of prizes for the ESOA champions were awarded at a ceremony after the event. 

This turned out to be quite a large event, and I really enjoyed being part of that and meeting some new friends as participants debriefed and re-lived their exploits up the hill. I was sorry to hear, though, that a small terrier stole the control-collectors' biscuits.

Final Details document available here. Please read the safety information and planner's mapping notes.

As well as being part of the SoSOL league, both the 2023 ESOC Club Championships and ESOA (East of Scotland) Championships (open to members of ELO, ESOC, EUOC, INT, KFO, RR, TAY) will be part of this event.  This event item includes all the information competitors will need about the area and getting to the event plus advice on which courses to enter to be part of this double championship event.

Prizegiving for the ESOA Club Championships will take place in the GTC car park (time TBC) and for the ESOC Club Championships at a social later in the day, details of which will be circulated to club members via ESOC Matters.

LOCATION OF THE EVENT: Corstorphine is on the West side of the city of Edinburgh but still offers great orienteering for everyone, whatever their skill or experience level of orienteering.  The event will be based (Registration and Download) in the car park at the GTC, 96 Clermiston Road, Edinburgh EH12 6UT.  Please note that parking is not available here, see below for travel options.

Facilities: There are no facilities ie NO TOILETS - Please 'go before you go' to the event. 'Informal toileting' is discouraged as this is a busy area for the public.  There are numerous options for calling in at a supermarket or shopping centre on your way to the event. 

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.  

Map: Based on 2019 version by  Peel Land Surveys, updated in 2023. The map has been extended to include some local quiet residential streets which only the longer courses will visit. M/W16s may enter the courses that make them eligible for the ESOA Championships ie Blue and Green, and should be aware that some road crossings on the residential roads will be marshalled.

The map will be printed on waterproof paper, the control descriptions will be printed on the map and there will be loose control descriptions at the Start. The map scale will likely be 1:5000 but the scale and size will be confirmed in the final details..


  • Dress: Please check the weather forecast on the day and dress appropriately.  This event is in the city, but it is November and the weather could be very cold, windy and wet.  It can also be very slippery on the area.   We recommend full leg cover for all competitors. We also strongly recommend that competitors on courses other than white and yellow wear studded shoes if they have them, as the steep slopes can be slippery in both wet and dry conditions.
  • Other Users:  The area is very well used by the general public, including dog walkers, runners, families out for a walk and even bikers.  Please respect their right to be there at the same time as you are orienteering. 
  • Dogs: Dogs are allowed but should be kept under very close control at all times.
  • Course Closure Time: Please note that courses have a closure time of 3.00pm after which controls will start to be brought in. All competitors should be back at Download by 3pm. At this time of year this is especially important as we don't want to be bringing controls in during darkness.
  • You must report to Download even if you do not complete your course so we know you are back safely (and don't need a search party).
  • An emergency phone number will be printed on the map

 Covid: Please don’t come to the event if you have Covid or symptoms of Covid.

Please also try to:

1. Respect other people's personal space at all times;

Explanation of colour courses

  • 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.
