Burnham Ace of Herts

These details are highly provisional based on our last Burnham event and are still to be confirmed.

Welcome to the Ace of Herts, Hertfordshire Orienteering’s biggest event of the year, 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.

We thank the City of London Corporation for allowing us to use Burnham Beeches and Portman Burtley Estates for allowing us to use Egypt Woods.

Directions From M40 Junction 2 (Beaconsfield) take the A355 S towards Farnham Common. Take the first exit on right, Burnham Road (2m width restriction), and follow O signs to Park Lane. Parking at SL1 8PL.

Coaches continue on A355, turn right onto Beeches Road at Farnham Common, then left onto Bedford Drive, follow this to Hawthorn Lane, then right onto Pumpkin Hill. At next junction turn right onto Park Lane and follow O signs.

From the S approach on A355 and turn left on Burnham Road 500m before the M40 junction, then follow signs as above.

Parking £?? parking charge collected at the gate. Follow the directions of the parking marshals.

The entrance to the field is single track and a one-way system will be operated. If conditions are very wet, you may be directed to the reserve parking, in a nearby field.

Terrain Egypt Woods, the northern part of the map, is a mixed commercial woodland on either side of a broad valley. It is mostly very runnable, though with bracken and brashings in some areas. There are relatively few paths. The shorter courses are wholly within Egypt Woods.

Burnham Beeches, the southern part of the map, is an ancient, predominantly deciduous woodland with some complex contour features on the sides of a valley. Again runnability is good apart from some areas of thicker woodland and holly thickets. The longer courses also visit this area.

Bracken which is not mapped is fairly low lying and does not significantly impede progress or visibility. The undergrowth screen, which is limited in use, generally signifies brambles and windblow.

Rootstocks are not mapped and neither are isolated holly trees which can be easily avoided with only minor deviation.

Due to recent wet weather, at the time of writing, some water features are larger than mapped and some usually dry features are water logged. Their exact appearance will depend on the weather in the week before the event.

Gates will be encountered in some areas of Burnham Beeches. Please close them after passing through.

Map Updated 2019 by Susan Marsden (Burnham) and Simon Errington (Egypt). Scale 1:10,000 with 5m contours. Waterproof paper.

A4 for courses between White and Green inclusive. Slightly larger than A4 for all other courses. Control descriptions are on the same side of the map as the course.

The Black and the Brown course are each split between the 2 sides of the paper.

Out of Bounds
These are denoted by olive green or by magenta cross hatching. Do not cross them, irrespective of whether the line between controls passes over them. The courses have been planned so that there is no advantage in crossing any of these areas. They include:

  • Swallow holes – dangerous (see Safety section)
  • Marshland (Black and Brown only) – ecologically sensitive mire.

Additionally, the southern perimeter road is out of bounds in its entirety and this is emphasised with magenta crosses in certain locations.

Fence Crossing
There is a 3 wire barbed wire fence running east-west along the boundary between Egypt Woods and Burnham Beeches. However, non-mandatory crossing points have been marked on the map and it is recommended these are used to avoid injury. Two are existing footpath crossings to which some red and white tape has been added. Others are simple temporary crossings where the barbed wire has been protected with foam pipe insulation. These are also marked with red and white tape.
Safety Swallow holes appear as very large wet depressions, usually fairly overgrown. Anybody entering them is at risk of drowning. They are marked as Out of Bounds on the map, but the best advice is: Do not enter any feature looking like this unless you know there is a control there. Even if your course goes near one (White and Yellow do not), the best route is always to the side of it.

Whistles are compulsory for all competitors and a check will be made before starting.

Full leg and torso cover is mandatory. In the event of bad weather cagoules may be compulsory – signs will be exhibited on the route to the Start before you leave the arena.

Competitors should be aware that, in addition to the general public and dog walkers, horse riding and cycling takes place in Burnham Beeches. Please take care and be respectful of others in the area.

An emergency number is printed on the map (Organiser)
