Welcome to the CLOK web site, which contains information for orienteers – and potential new orienteers – in the Cleveland area.

Latest News
The next Summer Series evening event will take place in Geneva Woods, Darlington, on Thursday 2‑Jun‑2016.  Follow the links for details.
CLOK's next training event will take place at Live Moor Plantation, near Swainby, on Saturday 25‑Jun‑2016.  Watch this space for details.


  • The CompassSport Cup heat at Timble Ings has been rearranged for Saturday 4‑Jun‑2016.  Follow the link for details.  Please use the on-line entry system to put in your entry no later than 23‑May‑2016. (CLOK will pay your entry fee.)
  • A plea for event officials.  Due to a combination of injury and holidays, two of our coming events are lacking officials, and one is in danger of having to be cancelled.  Follow this link for further information.
  • If anyone is interested in joining a 5 or 7 person CLOK team for the Harvester Relays – which will take place near Cheltenham over the weekend of 25/26‑Jun‑2016 – please contact Alan Cranke via 01642-554159.  CLOK would pay the entry fees and arrange shared transport and possibly somewhere to stay on the Friday night.
CLOK orienteering tops and sprint vests are available.  For more information visit the Members' Area.

From the webmaster

One of my main aims is to make this web site a comprehensive source of information for Cleveland-based orienteers.  In particular, you should be able to find information (or links to information) about all the events that are likely to be of interest to orienteers living in the Cleveland area.  This includes our own CLOK events, of course, but it also includes (a) all other events within reasonable traveling distance and (b) major events -- like the JK, the Scottish 6-Days, etc. -- that are likely to be of interest to CLOK members.  With this in mind, if you find anything missing from the site then please let me know.

I set up RouteGadget in October 2006, so competitors at CLOK events can now view the course maps, enter their routes, view other competitors' routes and watch animations showing how they and their competitors progressed around the course.

If you have any views on which developments should be given priority, or if you have any other ideas for improvements to the web site, then please contact me.

Also, if you find any broken links or errors then please let me know.
