DIY Street-O

Urban orienteering activities for over-16s – participate for free at a time that suits you.

Not sure how to get started? See our Introductory Guide

For further guidance please see the Wiki page at

See below for a selection of Street-O courses available for running at any time. Some were created during lockdown, others are being released after our Street-O events.

We strongly recommend recording your track (via your phone & MapRun, or on a separate GPS-enabled device) and sharing via the MapRun results site.  Courses have been risk-assessed. For your safety you must read the pre-read information, and any additional safety information on the map.

Courses are available for DIY-O for all our 2021 events. These events are PIN-protected but the PIN is available on the map – this ensures you have all the safety and control information to hand!

Print out a physical map from the “map” link in the table above.

Check out how others got on through the “Results” link in the above table.

[Optional] Search in the MapRun6 app (before leaving home if you aren’t data-enabled) for the event (most are prefixed with “HH”).

For watch GPS traces you can upload these after the fact via the MapRun interface at

Some more detailed guidance about using MapRun6 is available at our Wiki and there’s also a generic MapRun quick start guide.
