Ashridge Ace of Herts

We welcome you to our biggest event of the year, the Ace of Herts, a National event which is a round of the South East Orienteering League. It’s not just for experts, there are courses suitable for everybody and help for newcomers.

Location Ashridge Estate, National Trust, Moneybury Hill, Ringshall, Near Berkhamsted, Hertfordshire, HP4 1LT.
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 latter is only visited to any extent by the longer courses. The going is generally very fast with some limited areas of denser woodland. There are a few small areas of brambles or denser vegetation that are not marked on the map, but these can generally be avoided. The major and large paths can be very muddy, making straight routes through the forest more attractive. The National Trust have asked that if you do run along paths, you follow the main line even if it is wet or muddy; running round the edges damages the vegetation much more.

Notices asking the public to stay on the paths because of deer management activity can be ignored and there will no such activity on the day of the event.

The area is much used by walkers (many with dogs and/or buggies) 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.

Safety Orienteering is an adventure sport. You take part at your own risk and are responsible for your own safety.

Longer courses cross roads. Take care crossing any road. The main B4506 is to be crossed at a timed-out, marshalled crossing point.

Climbing of fences is strictly forbidden.

You are advised to carry a whistle. In the 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.

Ponds and marshy areas may be deeper and muddier than you think. Paths can also be muddy. The National Trust have asked that if you do run along paths, you follow the main line even if it is wet or muddy; running round the edges – even if others have done so before you – damages the vegetation much more.

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.
