NightChailey CommonSat 19 December, 2020

Near: Chailey
Level of event: Local
Type of event: Race, Night, Juniors



It’s always a pleasure to be able to organise a night event, so thanks to those that made it possible: Joe Barrett for the SI and Rob Leathley for control collection. Also, to Alex and Edward for hanging and collecting and to Alex for controlling.

Thanks to everyone that supported the event. We were lucky with the weather and the rain didn’t arrive until the last finisher had come in. Afterwards someone commented that night events provide a navigational challenge in terrain that might otherwise have started to feel a bit familiar. I’m sure that’s true, and it would be great if we could squeeze a few more night events into the calendar before the end of March.

Merry Christmas and a Happy New Year



Is a web app for sharing and comparing orienteering routes. You can draw your own route or upload a GPS track from your watch. It also allows you to watch an animated replay with a simulated mass start.

Pre event info

Entries are formally closed, but you are welcome to email the planner to see if any maps remain.

Late notes:

1. Parking is now available both the start/finish and at Chailey Heritage (see map below).

2. The start/finish is on playing fields that have recently had three large areas fenced off to protect the playing surfaces. Routes around these unmapped areas are reasonably obvious.

3. The playing fields are waterlogged in some areas, along with the adjacent footpaths. After that, conditions do improve.

A night event open to orienteers with previous experience of night orienteering. Chailey Common offers a technical challenge which is even better after dark. The Brown and Blue courses include road crossings and are open to juniors who have passed their 16th birthday. Juniors M/W16-M/W20 are required to wear hi-viz to compete on these two longer courses. Whistle and a back-up torch mandatory for all.

SIAC (contactless) punching will be enabled. Controls may be relatively close to each other, so please check your control codes.

Road crossings will be timed out. You should cross as soon as it is safe to do so, and should not look at your map during the road crossing time-outs.

It is hoped that live results will be available via wifi in the download area.

Terrain Description

Mixed terrain of open common and woodland. Areas of significant technical complexity. The Brown and Blue courses visit the western part of the map which is wet under foot.

Chailey Common is one of the largest commons in the south of England and was designated a Local Nature Reserve in 1966. The common is a Site of Special Scientific Interest for its heathland plants, and diverse insect and bird communities.

Chailey Common stretches over 180 hectares (450 acres) and includes Red House Common, Memorial Common, Romany Ridge Common, Pound Common and Lane End. Chailey Common is dominated by heathers. These include Bell and Cross-Leaved Heather but mostly Ling Heather. There are small colonies of blue flowering Marsh Gentian, Bog Asphodel and Sundew as well as beautiful summer displays of Heath-Spotted Orchid.

The heather and gorse provide a habitat for many birds including the Stonechat, Yellowhammer and Linnet. The Nightjar and Hobby are also regular summer visitors. The commons are also home to several of our native reptiles, such as adders and common lizards with many small ponds providing homes for a variety of amphibians.
