Regional Event - Colour-coded courses
Incorporating the Club Champs for BKO, MV and SN.
Start times are from 10am to midday.
There is no organised parking, you are free to arrive how you will. There is plenty of free-on-Sunday road parking within walking distance of the event centre at the west end of Chantry Wood (What3Words ///tend.jumps.slime)
PLEASE NOTE: the Brown course has more than 30 controls, so you cannot use a version 5 (numbered 1 to 500,000) or version 8 (2,000,000 to 2,999,999) SI card, as these can record no more than 30 punches. If your SI card is inadequate you can hire a SIAC to run Brown (our hired SI cards will not hold more than 30).

Event Information
Please make yourself aware of the British Orienteering Participant Code of Conduct (revised August 2021). By entering the event you have agreed to abide by it.
The area is used for walking and horse riding and cycling. Be courteous towards other users you do encounter, especially those with dogs and horse riders – our future use of these areas depends on this.
Travel to the event
Come to the Event Centre, at the west end of Chantry Wood (What3Words ///tend.jumps.slime).
You can take the train - there are two stations in Guildford, but a not insignificant walk.
There are buses.
If you are driving, be aware that the A281 (Shalford Road) will be closed from 10:45 to 11:15 on Sunday morning, south of Pilgrim's Way (I assume in Shalford).
If you come by bike there should be room for you to leave your bicycle near the portaloos (preferably locked).

There will be a small tent in which you can leave your belongings. Use a distinctive bag as it is likely to become a 'heap' of stuff.
Car parking is up to you - but NOT in the small Chantries car park
Do not park in the small car park near the Event Centre, which shall be kept clear for non-orienteers to use.
We would discourage parking along Pilgrim's Way and Echo Pit Road as these are a busy through route. There is ample space on Chantry View Road, Clifford Manor Road and Tilehouse Road in limited parking bays (which are unlimited on Sundays) and on single yellow lines (again not applicable on Sundays) - these are all within easy walking distance of the event. Please park considerately, these are residential streets, and ideally I suggest we try to park on only one side of the road to avoid chicanes.

Planner's notes
The Chantries and St Martha’s Hill lie adjacent on east/west walking routes; the more ancient Pilgrims Way skirts them but the North Downs Way enjoys a view of the Weald from St Martha’s church at the high point. They both form significant lumps of sandy, pebbly land, which is reflected in the height gains on all courses. The Very Short Green is planned to avoid the steepest parts. There is plenty of clear “white” forest, but expect the usual variety of runnability in partially shaded areas: the “undergrowth, walk, good visibility” symbol mostly describes bramble varying up to impenetrable. The dying bracken is not mapped: it may still present some hindrance on Blue and Brown courses. There is a good network of mapped paths, but additional vague and temporary ones come and go.

All courses explore the Chantries. Blue and Brown extend into St Martha’s.
Maps
Maps are A4 at a scale of 1:7500 with contours at 5m intervals.
Special symbol: a black X on the map represents a hide.
Brown and Blue courses start with a one sided map (Part 1); then at a map exchange point you pick up a double sided map for Part 2 and flip it over for Part 3.

The event is on Remembrance Sunday. We shall cease activity at the Start just before 11 o'clock and resume after the 2-minute silence at 11.
All must punch the Start, including SIAC (contactless) dibbers. All other controls (except the Finish) are enabled for SIAC 'swiping'. It is your responsibility to check your SI card has registered at each control. In case of SI failure use the pin-punch on the control stake to mark your map in one of the R(eserve) boxes.
Take care of your hired dibber. It will cost you £69 for us to replace a SIAC if lost (or £20 for a normal one).
Courses summary information
Note the 3 maps for Brown and Blue are presented as Part 1 on one sheet (from Start to map exchange) then Parts 2 and 3 back to back on a second sheet (from map exchange to Finish).

If you are travelling on your own so there is no-one checking that you complete your course it is recommended that you leave your car keys (or something else you won't forget to collect) in the car key box at Enquiries, with your name attached. So if you somehow slip through the net of our safety checks we still have an indication if you are missing at the end of the event.
It is strongly recommended that you carry a whistle. To attract attention in case of an emergency.
Safety bearing if you get lost is to head west and north (without leaving the woods).
Maps are overprinted with an emergency phone number which can be used on the day to contact the Organiser for emergencies.
Nearest A&E is Royal Surrey County Hospital in Guildford. There is a map at Download. There is also First Aid at Download.
Competitors take part at their own risk
