Map  1:10000 with 5m contours, updated for this event. Note that the major works that were taking place during the last event here are now formally complete but there may be some contractors’ equipment remaining.

Avoid all areas marked out of bounds, including the new children’s playground and pool areas. Areas marked with the purple out of bounds symbol are recently sown grass, they are marked with temporary plastic fencing but those fences are not shown on the map.

The golf course to the west of the map is out of bounds.

Facilities Toilets in event centre. The ones near the start & finish were demolished at the end of June.
Dogs  Dogs permitted, but must be kept under control at all times and NOT ALLOWED ON THE RUGBY PITCHES at the event centre.
Safety The river and canal are deep; the river can be very muddy and the canal carries barge traffic. Use bridges – marked as crossing points on the map – to cross all bodies of water shown with a black border.

Please show respect to other users of the park.

Orienteering is an adventure sport. You take part at your own risk and are responsible for your own safety.
