Thank you for attending the event. Despite the weather forecast there was thankfully little rain after the organising team got soaked while setting up everything prior to the arrival of the competitors. Fortunately we managed to pack away everything before the rains came back.

Some new temporary fencing appeared only a day or two before which we were unaware of until the morning of the event. All we could do was to make a note of it at the Start. 

Most people seem to have enjoyed their run which always makes all the hard work that goes into staging an event worthwhile.   


Thanks go to the organising team: Graham Batty (Planner), Colin Jackson (Organiser), Paul Beckett (on the day Controller/control checker), Janet Biggs (Controller) and volunteers: Barbara Beckett, Dale Bennett, Tony Biggs, Guy Lidbury and family (Charlie, Hugo and Amelie), Michael Muggeridge, Garry Parmenter, Chris Shaw, Andrew Welsh, Richard Wilkes and Olive.


This event incorporates the first rounds of both the 2019/20 SWELL (South & West Essex Local League) and ESSOL (Essex and Suffolk Schools Orienteering League) seasons. 

We welcome Chigwell and Epping Forest Orienteering Club (CHIG) and Dartford Orienteering Klubb (DFOK) for their respective club championships. 

The event is open to all orienteers and newcomers are especially welcome to come and try some orienteering in a friendly atmosphere.


Final details updated 26/09/2019 to include a note about the width restriction in the car park.
