Please read the Final Details at the above link, it has key event information.
The Chiltern Challenge is TVOC’s premier event of the year. We are delighted to be able to use the mature Chiltern woodland and slopes at Bradenham, Park Wood, with longer courses also making use of Naphill Common. We appreciate the kind permission of The National Trust, Friends of Naphill Common and Mr A Stubbings to use these areas.
This event incorporates this year’s SCOA Championships and is a Junior Interland Selection race. If you think you are eligible for the SCOA Championships or are a junior wishing to be considered for Interland selection, then read these notes carefully before you enter. Entries for the SCOA Champs and Junior Interland events close on the 3 December.
Update 4 December We have now placed our order for map printing. Entry numbers for each course are therefore now strictly limited. However we have ordered a good number of extra maps, and thus hope to keep entries open right through to Sunday morning. If you need to amend your entry, please contact Alun at firstname.lastname@example.org

This area has been used for the British Middle Championships in 2015 and the BUCS individual race in 2019. The competition area comprises of mature beech woodland and is fast and undulating, with some steep chalk and flint slopes with a complex path network.

There are two starts. The near start for Light Green and below is 400m away. The far start, for all other courses, crosses a road (not marshalled) and is 1km away.
The event is using Si, it is a Punching Start with all other controls being SiAC enabled. A safety control after the finish has to be punched.

Black – Last start 11:45

Very Short Green and above courses have an unmarshalled road crossing on the way to the Start, and a timed out marshalled road crossing (national speed limit applies) on the course. Those that are M/W14 and below are advised not to enter courses above Light Green due to this road crossing. However Interland top year M/W14s targeting M/W16 selection next year are able to 'run up' as required.
The RED course is particularly appropriate for runners who are new to orienteering (and can be run as pairs). It is a longer course but without the technical difficulty of the Green courses.
Non members of British Orienteering are welcome to participate on any course. Families and small groups would find the Yellow and Orange courses more suitable.
