Location Ashridge Estate, National Trust, Moneybury Hill, Ringshall, Near Berkhamsted, Hertfordshire, HP4 1LT.

The entrance to Monument Drive and the Estate Visitor Centre is off the B4506 between Berkhamsted and Dagnall at grid reference SP979127.

Terrain Ashridge is a fine area of gently undulating deciduous woodland with a steep scarp slope to the west containing some areas of contour detail. The going is generally very fast with some limited areas of denser woodland.

As it’s autumn, there are significant parts of the map where the runnability and visibility are much reduced, so those on Light Green upwards should expect to encounter patches of brambles, bracken and nettles even in some of the areas mapped as white, and in many of the clearings.  In those areas running round may well be the best option and anyone on these longer courses is advised to have good leg protection.  Also, courses from Light Green upwards cross Monument Drive at least once, so care should be taken.

The area is heavily used by walkers (many with dogs and/or buggies), runners, cyclists, mobility buggy users and horse riders. Please be considerate to them to help ensure our continued access to this area.

We would like to thank the National Trust, and Ashridge Estate in particular, for access to this excellent forest.

Parking Turn west into Monument Drive and follow marshals’ instructions. Parking will be in and around barrack square, half way down on the left.

Maps The map scale for this event is 1:10,000 with a 5 m contour interval for all courses. The area was resurveyed by Susan and Keith Marsden in spring 2018 and final updates added in January 2019. Some small seasonal animal tracks are not shown, nor are rootstocks, timber stacks, small fenced enclosures surrounding one or two trees, or branch hides. Thickets shown are generally (but not exclusively) rhododendron or holly.

Loose control descriptions will be provided.

String course The string course is located east of the main parking and the main start.

Go to network hhresults. There is no password.

Full results will be published on www.herts-orienteering.club and Routegadget as soon as possible after the event.

Safety Orienteering is an adventure sport. You take part at your own risk and are responsible for your own safety. A full risk assessment has been carried out.

Climbing of fences is strictly forbidden.

The Light Green course crosses Monument Drive once, Short Green and upwards cross it twice. It can be busy on a fine day, but with slow-moving traffic. Visibility is good except around parked vehicles, so take care.

The Ridgeway run passes through our competition area earlier on. Our courses have been planned to minimise interaction, but if you encounter someone on a trail wearing a race number, please give way to them.

Competitors travelling alone are advised to leave something of value that they will not forget at Enquiries (e.g. car keys). All competitors are advised to carry a whistle. In the unlikely event of extreme weather on the day, cagoules may be compulsory and you will be informed by car park marshals and in Assembly. Come prepared.

Large numbers of deer live in Ashridge; please allow them to move away from you without chasing and panicking them. If ever a deer does not move away from you then it is injured and should not be approached.

The area is popular with cyclists, dog walkers and horse riders. Please show them due consideration.

First Aid will be available at Assembly. The nearest hospital is the Luton and Dunstable Hospital Trust, Lewsey Road, Luton LU4 0DZ, 9 miles from the event. Maps will be available at enquiries.

You must go to Download (in Assembly) even if you don’t finish your course. We need to confirm you’re back safely.
