PLANNER’S COMMENTS: Alison Cunningham writes - Planning the courses on Corstorphine Hill was fun and I hope you all enjoyed the Hill nearly as much as I do.  I tried to keep you in the nicest bits but inevitably there had to be slippy, hilly and brambly parts, although the weather and the paths were about the best I have seen in recent weeks! What fun I had creating a path through the brambles in a blizzard and sliding down the slopes backwards during storm Ciara! As much as I loved the planning I found the computer techie bit much more difficult and my huge thanks to Martin for all his help and patience in creating such a pretty map which was printed on time! Although slightly embarrassed by the enormous size of the map and equally enormous size of the control circles I only heard favourable comments about the clarity of this - many thanks to those who didn’t have a moan! 

My apologies to the wee ones on the white course who spent most of their course in the full force of the cold Westerly breeze and to those working on the start which also had little shelter. I was interested to hear all the different course route choices and even some I hadn’t thought of - apparently the mid-green vegetation wasn’t too bad to get through even if it looked pretty awful to me; although some will fight through anything to avoid losing height! I was sad that nobody I had spoken to had spotted the wallabies from the crag on LG/Bl/Br courses but was delighted by the many really favourable comments - there are some lovely wooded areas on the map at this time of year. All participants were accounted for at the end, which is always a good thing, although to the 3 who finished after some considerable time on the LG course  - don’t assume No 7 will be in the same place at the CATI event on the 14th March!

Many thanks to Anne for hassle free and beautiful organisation and for a really lovely string course in an area of the woods that I have never ventured into and was really pretty. And many thanks to Martin and Ken for helping put out the controls and to Helena, Hanne, Dave, Crawford, Sally, Katy, Alastair and Peter for collecting controls in. Special thanks of course to Ken for checking my courses and keeping my right throughout. 

While I was putting the controls out I realised just how much I love seeing a control kite sited in the woods and as I sat and watched everyone dashing about around me was reminded what a great sport for all orienteering is.

Thanks for coming!

General Information

UPDATED FINAL DETAILS are here. These were added to the website on Thursday 20th February and contain extra information, including details about SIAC being enabled and about start times.  For ease of reference for those who read the original Final Details the new bits are shown in italics.

LATE NOTE ABOUT MAPS (not in Final Details) Due to high demand in the last hour before entry closure we have printed additional paper maps on all courses so that we can cater for on the day entry. These have been sealed in polythene bags (like the old days!!).
All maps will be together at the start so if you have a map preference an earlier start would be best.

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.
