CLOK logo

Parking will be in the Bassleton Court Shops car park, adjacent to The Griffin pub in Thornaby.

At the "spitfire roundabout" on the A1045 in Thornaby, turn west on to Bader Avenue.  Just after passing The Griffin pub on your right, turn right into Newton Road and look for the car park on your right.  The grid reference of the entrance to the car park is NZ 450156 and the What3words reference is ///stove.leaned.scan.  The Griffin's postcode is TS17 0EH.

Click on the link to see a map.  You can zoom in (and, optionally, switch to Satellite mode) to see the details of the final approach to the event.  You can also get directions if you specify your starting location.

If the car park is full, please park considerately on nearby residential streets.


This is the first event in this interesting area, which is about 60% urban and 40% woodland.  Thanks to Stockton Council for bringing the area to our attention and giving us a grant to cover the cost of creating the orienteering map.

The competition area includes quiet residential areas, some of which are surprisingly complex, as well as woodland and rough open areas.

It will be to your advantage to read the Planner's notes on the terrain and advice on course selection.

In particular:-

  • Anyone under the age of 16 on the day of the event must be accompanied by an adult if they are running any course other than Yellow, Orange or Light Green.
  • Children under the age of 12 on the day of the event must be accompanied or shadowed by an adult, because the courses involve going along a path that runs close to the deep water of the River Tees.
  • There are two sections of street that are marked as out of bounds.  If you are seen going through one of these out-of-bounds areas – or if we can tell from your split times that you've gone through an out-of-bounds area – then you will be disqualified.
  • As always, please be courteous to the members of the public who are sharing this area with us.
Course  Length  
Short Green3.545
Light Green3.440

Please note that the course lengths have been measured along straight lines between the controls.  Unless you can leap tall buildings – and, in come cases, a loop of the River Tees – in a single bound then you will run significantly further.  For example, the Planner reckons that the optimum route around the Brown course is slightly more than 9 km.


This event is using a brand new map by Dennis Hooton.

The map scale is 1:5,000 for all the courses.   The Orange and Yellow maps are A4.   The Brown, Blue, Green, Short Green and Light Green maps are A3.

The control descriptions will be printed on the maps, and loose copies will be available at the Start.

Punching system:

SPORTident electronic punching will be used.

The control boxes will be activated to enable SIAC cards to operate in touch-free mode ..... but please note that you will need to punch the old-fashioned way at the Start and Finish.

SI-cards will not be available for hire on the day.  However, you can reserve a hired SI-card during the entry process in Racesignup.  There is a £1.00 hire charge.  You can collect your hired SI-card – which will be in an envelope labelled with your name – from Download car before your run.  Please remember to return it as you download.  There will be a £20 charge if you lose your hired SI-card.


There will be no Registration and no entry on the day.  If you wish to participate in this event you must pre-enter via the Racesignup online entry system.

  • The first entry deadline is midnight on Thursday 5‑May‑2022.
  • After that, you will still be able to enter until midnight on Thursday 12‑May‑2022, but there will be a late entry surcharge (£1 for seniors; 50p for juniors) and your choice of course may be limited by map availability.

The new entry deadlines should help us minimise our map wastage.

The Organiser has decided to accept entries at the event, subject to the availability of maps.  Entries will be taken at the Download tent, adjacent to the Start and Finish.

There will be no cash refunds, but if you cancel your entry before the final entry deadline you will receive a refund in the form of credit paid into your CLOK Racesignup account.

Although the Covid-19 restrictions have been relaxed and the Omicron wave has (mostly) subsided, the pandemic is not yet over.  Please continue to take precautions to protect yourself and other people ..... including the volunteers who make orienteering events possible.

Orienteering is an outdoor, naturally socially-distanced sport.  However, although you should be relatively safe when you are out on your run, there is a risk of Covid-19 transmission during the pre- and post-run activities.

Given that:-

  • Please do not attend this event if you have Covid-19 symptoms.  In accordance with Government guidance, if you have Covid-19 symptoms you should stay at home and avoid contact with other people.
  • Please maintain effective social distancing, including from the volunteers on the organising team; e.g. at Download.
  • Before and after your run, avoid unnecessary close contact with people outside your household.
  • Maintain good hand hygiene.

Please make sure that you download even if you do not complete your course.

A comprehensive risk assessment will have been carried out by the organising team, but please remember that competitors take part at their own risk.  Orienteering is an adventure sport – your safety while orienteering is your own responsibility.

CLOK strongly recommends that you carry a whistle at this (and every) orienteering event.

If you have a relevant medical condition, please add this to your competitor details in Racesignup.  Any information provided will be treated in strict confidence and will only be used if you need medical treatment and are unable to communicate at the time.
