Map: survey and cartography by Robert Griffiths (2018-2021) with some minor updates by Bill Marlow (2018-2021). Map Scale: 1:5000 to give greater clarity. There are quite a few paths, which act as good line features providing the Orienteer the ability to relocate (establish where they are on the map) quickly.

Because of the current Covid-19 regulations this event will be run as a virtual orienteering event. Hence you will need a smartphone with an App called UsynligO, which can be dowloaded from the internet using either of these links:

Instructions as to how to use this App can be found by clicking here.

Some important points:-

Entries only through Fabian4 and will be limited to 50, no entries on the day. Click on this link, find the event listed under Orienteering and finally click on "Enter".

Waterproof maps will be provided on the day to all competitors who have entered, you will also be able to see the same map on your smartphone if you prefer to use this.

Time slots will be allocated when you enter, please keep to these as we are trying to keep social distancing.

The only Club official available on the day will be the Organiser and Planner Bill Marlow. To avoid physical contact, maps will laid out in marked plastic trays, which Bill will point you to. Please keep the social distancing of 2 metre at all times.

Unfortunately the software does not allow the central recording of results but you will be able to view your results against the other competitors running your course by clicking on results tab on your UsynligO App after everyone has finished.
You will need to change your smartphone settings under display & brightness sub heading sleep to never sleep.
Allow UsynligO App to access your location at all times.
In the App settings set your control radius to 15 meters and minimum GPS accuracy to 100 meters

COVID-19 pandemic, please note the following

Please remember to stay safe and to stay within the governments guidelines on social distancing.

We hope that you enjoy the event, but please be mindful of your own health and others, we ask that you will:

Heed the current government restrictions for example if you have a pre-existing medical condition
Keep yourself safe, but also be aware and keep any members of the general public safe, so hand washing is important and do consider this as technical training not a race - always give people you encounter 2 meters of space - if you need to divert or stop and wait, please do so
Support the government’s efforts to manage the infection.
If you have any questions regarding the use of the software, which has not already been covered please let me know and I will try to answer them. You can contact me by email -
