The Chiltern Challenge is TVOC’s premier event of the year. We are delighted to be back in the beautiful Chiltern woods of Penn, and are grateful to the Woodland Trust, Earl Howe, and Penn & Tylers Green Residents Association for kindly allowing us access for this event.
This event incorporates the 2024 SCOA Championships. If you think you are eligible for the SCOA Championships, then read these notes carefully before you enter. Entries for the SCOA Championships close on the 17 March.
Directions / Parking
The event is at Penn Street, which is signposted off the A404 between High Wycombe and Amersham, at SU924965, HP7 0QW.
Parking is at commercial premises at SU923956, adjacent to the Hit or Miss pub, Penn Street, HP7 0FA. No charge for parking - your entry fee includes a donation to a charity of the landowner's choice.
Parking is very limited, so you are urged to share cars with other club colleagues. We would welcome competitors selecting very early or very late start times in order to allow double use of car park spaces.
Travel by public transport is via High Wycombe or Amersham, both of which have trains from London. There is then an hourly bus service to the Penn Street turn-off on the A404, followed by a 10 minute walk.
Penn Wood and Common Wood are both ancient woodlands. Penn Wood is generally flat, as are most of the Penn Estate and Common Wood but the latter does contain one steep slope. The woods are very varied with a mixture of conifer, beech and oak, and some open areas. There are many pits / depressions as a result of ancient clay and flint workings.
Last used for the Chiltern Challenge in February 2019.

Penn Wood is pretty much flat, so courses Red, Green and below will have minimal climb. Courses Short Blue and above cross into Common Wood and Penn Estate where there is some climb - around 150m for the longest courses.
Short Blue and above courses have two timed-out marshalled road crossings (50 and 40mph speed limit respectively) on the course, and an unmarshalled road crossing (30mph) on the return from the Finish.
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.
Newcomers are very welcome to attend this event. Please contact the organiser if you are unsure which course to enter. Families and small groups would find the Yellow and Orange courses more suitable.
