Maze combined with Park orienteering

Sun 22nd Aug 2021

Info updated: 23rd Aug
Type of event: Local
Type of terrain: Parkland


Provisional results can be found here and the cumulative results here.

Organiser, Janet Clark writes:  The Ultrasprint is a fun event for the competitors, but it also has several unique complexities in execution. These were tackled with aplomb by the Maze-setting Team, the Control-placing Team and the Computer Team (ie Gordon), all skilfully  overseen by Sabine, who acted as both Planner and Controller on the day. 

This particular event was originally planned for two years ago by Callum Tyler who has since moved to France, and was carefully updated and amended by Sabine and Simon Gregersen, together with the original Controller Roger Scrutton.

The action started slowly and gathered pace as people started their second and third runs, got the hang of the Maze, and warmed up enough to put in good efforts on the uphill run-in to the Finish, cheered on by the onlookers.  Then at the end the competition for the fastest time for the Maze-only got pretty fierce.  How could anyone possibly do it in under two minutes? 

Grateful thanks to the very well-oiled team of helpers who set up and dismantled everything so smoothly, and to the Inch park Community Centre for letting us add orienteering to the wide range of other activities happening at the same time.

General Information


BACKGROUND: The Ultrasprint is a fun event for what is anticipated to be our first formal event post Covid restrictions.  Hopefully the restrictions will have been relaxed enough for this to include a social element and if this is the case, and the weather is kind, we encourage everyone to bring a picnic and socialise.

EVENT FORMAT: Controls in a Maze combined with some park orienteering. The challenge is to navigate around the controls in the Maze quickly and cleanly. The fastest runner may not be the most accurate. It is entertaining for the spectators and makes a very welcoming, sociable, fun event which everyone can enjoy.

TOILETS: Nearest toilets in Cameron Toll shopping centre which adjoins Inch Park. 

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 or handed back to you after the event.

All Courses close:  16.30

Course Information

There will be 4 separate courses. Courses 1, 2 and 3 will each be around 1 - 1.5km in length and all visit the maze at some point.  These courses will not have control codes in the second column of the control descriptions.  It is up to you to make sure, by accurate map reading, that you are at the right control. The winner's time is the combined time for Courses 1, 2 and 3. A penalty of 2 minutes will be added to your time for each control wrongly punched. 

You will be allocated to a course for your 1st run at 'check' then join the other queues when you come back for your 2nd and 3rd runs. In the past maps have been re-used and you only got to keep one copy; this year you will be given a new map each time, plus a maze map, and can keep them all.

The maze only course will have control codes in the usual way. 

Inch Park is heavily used by members of the public, including dog walkers and others playing sports. Please be considerate to them and also to other orienteers, particularly in the maze.

There are sports pitches in Inch Park.  The date has been chosen to minimise contact with others however if games - even informal games - are happening please respect their right to be 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.
