Tamar Triple 2018

Bank Holiday Weekend 26th - 28th May 2018





Day 1

Exeter University Streatham Campus


This is located within the historic city of Exeter, and the event is confined to the university campus.

All courses will cross areas of grass and rough open. Elsewhere the running will mainly be on hard surfaces.


Days 2 and 3

Braunton Burrows

Braunton Burrows is a complex area of sand dunes presenting challenging orienteering and is designated a UNESCO Biosphere Reserve.

This map was used for the 2010 JK at 1:15k and 1:10k.

The area is used for military training - especially by vehicles. This means that there are a multitude of tracks going through the dunes. For clarity the symbol used for 'paths' on the map is one category less than normal - e.g a major path/track is shown as a minor path, and minor paths as 'indistinct'. Also many new tracks appear after each military exercise, so be prepared to find unmapped tracks especially in the slacks (large low-lying areas).

Marshes/surface water can appear in the slacks when the water table is high. However the level varies not only with the tide and rainfall, but by area - one slack may have surface water in whilst another is dry. At present the most regularly affected areas are marked as seasonal marshes, but these may be left off the map if we have a dry spell.

Vegetation is pretty stable on the majority of the dunes, and the undergrowth stripe symbols indicate general feasibility. However the land managers are regularly clearing the scrub throughout, but especially from the east side of the map. The map will be updated within 4 weeks of the event; however competitors should not be surprised if some mapped thickets have disappeared - the fresh clearance areas are pretty obvious with shredded vegetation litter.

Tree areas are largely shown as green as they are usually difficult to get through.

Wind sand-blow: the worst areas of storm change are along the coast - not used in these events. However many inland dunes are affected: the big 'blow-through' dune has had sand thrown about 100m further East during this winter; what were small re-entrants on the W side of some dunes have now been blown out to become deep gullies, and new 'sandy areas' have appeared. As with the vegetation, be prepared for the occasional mapped feature to have changed, especially if recent storms (and military vehicles) have come through.

Fences: the whole area is divided into 3 zones for cattle grazing. Most courses stay within one zone; however if your course does go from one to another you must cross at the stiles/gates shown. This is a top class orienteering area - please do not be put off by the above comments. But compared to a standard forest area, where changes tend to be slow and seasonal, details in this area can alter very quickly.
