Terrain Description

Thorndon Park is an area of established mixed woodland with some open and semi-open areas and a good path network. Longer courses go into the southern area of fields and more recently created woodland. Unfortunately, as with many other areas, there are numerous small paths created by mountain bikes. We have  done our best to map these - usually as indistinct paths.    

The map is A4-sized at 1:10000. Control descriptions are printed on the front and all courses except Brown have the legend. Single purple X's on the map indicate gates that are locked. It is recommended to use an alternative crossing point nearby. Many of the fences are for controlling stock grazing and have two or three strands of barbed wire on top and will be difficult to cross except by the most agile competitors.

A black O on the map indicates a sculpture or a small fenced enclosure. None of these features are used for control sites.

White and Yellow courses have written descriptions, Orange has both written and pictorial descriptions. All other courses have pictorial descriptions.

START & FINISH  Approx. 1.4k walk to the start mainly along level forest paths, allow 15-20 minutes. There are two road crossings. Firstly over Eagle Way (use the zebra crossing please!) and a second nearer the start which we hope to marshal. However, under 16's need to be supervised. Similar walk back from the finish to the car park. There will be a clothing dump close to the start and finish. Items left at your own risk.
