Welcome to one of our Saturday series events. Beginners are very welcome and there are courses for all standards.

Cassiobury parkland

Runnable parkland with some wooded areas, some with significant undergrowth.

Full leg and torso cover required for Orange course and above.

PARKING Fullerians Rugby Club, Coningesby Dr, Watford WD17 3BD.  Please follow the parking marshalls’ directions.
PUBLIC TRANSPORT Watford Junction station 2.4km, Watford Metropolitan station 1.8km.
COURSES Courses for everybody from beginners of any age to experienced orienteers.

Course Straight line Distance Difficulty
White 1.5 km Easy – all along paths. Control flags when you need to decide whether to turn.
Yellow 2.0 km Fairly easy – navigate along line features such as paths, walls, streams.
Some turns with no control flags.
Orange 2.9 km Moderate – start cutting across country, some controls a bit away from line features.
Light Green 4.0 km Harder – a range of navigational skills needed to find controls on any mapped feature.
Short Blue 5.6 km As hard as we can make it on the area.
BEGINNERS First timers are very welcome. Look for our greeters in hi-vis jackets who will give you socially-distanced help.

If you’re not run before, we suggest most people start with yellow. Young juniors, say primary school age, and family groups are better on white. People confident with a map and compass may start on orange.

FACILITIES Toilets in the Rugby Club. Please bring your own drinks.
DOGS Please respect the sports pitches and keep dogs on lead / clear up behind you. No dogs inside the event centre.
SAFETY Orienteering is an adventure sport. You take part at your own risk and are responsible for your own safety. A full risk assessment will have been carried out.

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.

You should abide by the British orienteering Covid-19 Code of Conduct. In particular:

  • You should not come if you have symptoms of COVID-19, are required to isolate, are awaiting the results of a non-routine COVID-19 test or are serving a quarantine period after travel. You’ll get a full refund.
  • Before, during and after your run, maintain appropriate distance from other runners and other park users.
  • Hand sanitiser is available – please use it.
RESULTS Interim results will be published direct to the club website every few minutes during the event. There will be no printed results (apart from your own splits) or WiFi available, so there is no need to hang around.

Full results will be published to the same location and to Routegadget; we aim to do so on the day of the event.
