Directions / Parking

From the roundabout on the A416 Amersham Road at the South end of Chesham, turn SE along Moor Road.  After 300m turn right into the free public car park just before the outdoor swimming pool.  Beware, there is a 2.2m height restriction to the car park, but tall vehicles could park on Moor Road adjacent to the car park.

TVOC marshals will direct you to a car park space.

Alternatively, for those using public transport, Chesham Tube Station on the Metropolitan line is about half a mile away.

On leaving the car park you must turn left.  Turning right leads to a dead end, so beware of SatNav misdirection.

The car park opens at 9:30am.  Use of the car park is by kind permission of Chesham Town Council.

Terrain Description

The competition area is relatively small and on the southern slopes of the Chess Valley, so some contours. Course legs are very runnable amongst classic Chiltern beech woodland, with areas of holly fight to avoid, and a small open field with a lovely view over the Chess Valley. Low earth walls and a few depressions are links to the area’s past use. You will be no more than 60m from a path. Footpaths link a small southern section of woodland used by the longer courses of Red, Light Green and Green.

The Map

A4 map, scale 1:5000, based on Lidar data. Symbols are ISOM 2017- 2 enlarged to 250%.
The landowners require that we do not enter several small areas of sedge grass. These areas are all marked out of bounds on your map with purple hatching. Your optimum course routes avoid them. Please also avoid straying into the cemetery at the eastern end of the map which is also marked as out of bounds.
All courses cross through a broken steel spiked fence mostly buried on the ground and shown on your map as a thick purple line. Only cross this line on a path at one of the mandatory crossing points shown on your map and on your course description sheet.

Start Times

THERE WILL BE NO ENTRY AT THE EVENT. You must pre-enter, via SiEntries using the link at the top of this page. Subject to still having maps available, we will keep entries open until the morning of the event.
On the day, collect your hired SIAC dibber from the TVOC tent.
Starts will be from 10.15 to 11.45am.
There is a 400metres walk from the TVOC tent to the Start. The route to the Start and from the Finish requires crossing a minor road, so children should be accompanied. Follow tags from the TVOC tent. After the Finish Control continue a few metres to the manned check finish where each runner must insert their dibber. Continue to the field gate, turn right and continue downhill past the Start and retrace your route back to the Download Tent where you will receive your results slip.
Courses close at 1pm. All competitors MUST be back at the Download Tent by 1pm, whether finished or not.

How To Enter

PRE-ENTRY ONLY through SiEntries, using the link at the top of this page. There will be no entry at the event, though you will be able to enter right up to the day of the event if there are still maps available.

You don’t have to be a member of an orienteering club to enter this event. On SiEntries, just show your club name as IND (for Independent).

Small family or other groups are welcome, but please enter only the Yellow, Orange or Red courses. Just one entry will cover your group. You will receive one map. However we recommend you have one map EACH – you can order extra maps (£1 each) when you enter.

Facilities

Chesham Leisure Centre has been refurbished since we were last here and is adjacent to the parking area.  They are allowing us to use their toilets, but please don’t go in with spikes, and use the overshoes that will be provided by the entrance to prevent muddying their floors.  They also have a new cafe that will be available for hot drinks and snacks.  There is a small playground for young children between the car park and the leisure centre. Chesham town centre with all of its facilities is about half a mile away.

Dogs

TVOC’s policy is that dogs are not permitted on courses.
