SmartPhone Orienteering uses a smart phone's GPS instead of a dibber.
There are normally no control kites or punching units, although existing POC marker posts may be used. Instead, the phone beeps when you are close enough to the virtual 'control site'.
You follow the course either by using an on-screen map or a paper map you have printed from a downloaded PDF.
Start and Finish are likewise at virtual locations.
You can run a course at any time. Just arrive, prepare and go! However, probably best not to go running around villages and towns at hours that might concern residents.
The free application is called "MapRunF" and can provide some great orienteering action.
Download from your phone app store, install it and then choose a course you wish to do!
You can upload the results and compare them with anyone else who has completed the courses.
During the Covid19 pandemic, using the app means that you can orienteer in a socially distanced way whilst obeying any current restrictions on group size.
As with Permanent Orienteering Courses, there are no event officials present, so you are responsible for your own safety.
There is a full guide on the British Orienteering Federation website.
