General Information


Janet Clark, Organiser, writes:  After the last two days of continuous downpours, Corstorphine Hill in the winter sunshine felt very special and absolutely everyone was there!  Regular ESOC members, new ESOC members, several members we hadn't seen for quite a while, a huge group from the Mary Erskine School, friends from other clubs, some quite far away, complete beginners; old and young - everybody!

The organising team  was a wonderful combination of old hands and newcomers to the team, working together to the highest standards to give all competitors a great experience.  We shared the hill with an enthusiastic children's mountain-biking group, and there was room for all, with our extra marshals being hardly needed.
Thank you very much to everyone, competitors and helpers, who contributed to this most successful event.

Mark Sanderson, Planner writes: I am very glad the weather decided to change its run of form for Saturday!  Thank you for everyone who attended, I hope you found the courses fun and interesting.  My main aim was to avoid excessive climb on the shorter courses and hoping the paths were clear enough with the autumn fall.  My other aims was making the longer courses as technical as possible given the area and the path network. 

It was my first time planning and the whole ESOC team made it a great experience.  Peter helped enormously as Controller, lending his experience and wise guidance, many thanks.  Janet coordinating just about everything and kept things organised and ticking along, thank you!  To all the other volunteers on the day, you helped make the event happen and your dedication to ESOC and promoting orienteering was very impressive!  A final thanks to the control collectors, Sally, Crawford, Alison and Peter, your help avoiding a late finish was greatly appreciated.  A reward collecting in controls was seeing the monkeys in the zoo from control 226 (Blue and Green courses) playing around before their bedtime!




TRAVEL ALERT for day of event: Be sure to read the alert, relating to international rugby match, on Directions section below.

Interlopers urban event on Sunday 20th November

ESOC CLUB CHAMPIONSHIPS 2022 will be part of this event.  This event item includes all the information all competitors will need about the area and the competition generally.  Details of how the Club Championships will be managed will be communicated directly to Club members.

Location: 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.  

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.

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.  

Course Maps: The map will be printed on waterproof paper, the control descriptions will be printed on the map (no loose control descriptions) and the map scale will likely be 1:5000.

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.

Facilities: There are no facilities. 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. 

Course Closure Time: Please note that courses have a closure time of 4.00pm after which controls will start to be brought in. All competitors should be back at Download by 4pm. At this time of year this is especially important as we don't want to be bringing controls in during darkness.

TRAVEL ALERT: There is an international rugby match between Scotland and Argentina at Murrayfield at 3.15pm on same day as Corstorphine Hill event. This will affect much of the travel to and from Corstorphine Hill.  The area around Murrayfield Stadium, including Roseburn, should be avoided and an alternative route found to get to and from the Corstorphine Hill event. The attached map provides details given by the Council of the road closures/times. The link below to Lothian Buses website will be helpful for details of any re-routed services that day.  If this affects you there should still be plenty of options to get to Corstorphine Hill via an alternative route.

LOCATION OF EVENT: The event will be based at the GTC, 96 Clermiston Road, Edinburgh EH12 6UT.  Please note that parking is not available here.

There are plenty of options for getting there. Please use public transport or share cars if at all possible.

By Bus: Check Lothian Buses website to plan your journey. Other (out of town) bus services run along St John’s Road, Corstorphine and also Queensferry Road and these could be more convenient. Get off at the stop nearest Clermiston Road to walk to the event.

Registration & Start Times

REGISTRATION: will be open from around 12.45pm until 2.15pm. Registration and Download will both be in the GTC car park.  We will be sharing the car park with a cycle club which meets there every Saturday so it is very likely that only a very few helpers' cars will be allowed to park there.

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.
